The financial pathway to green manifests itself as a dichotomous and mutually-exclusive choice between a hybrid car which entails fossil fuel directly and an all-electric car which doesn’t. This exercise frames the decision-making process into a typical mutually-exclusive capital budgeting analysis. We choose Toyota Prius as the hybrid and the Nissan Leaf as the all-electric car.

In August 2015, a Toyota Prius lists at $26,985 as its manufacturer suggested retail price. The corresponding retail price for the Nissan Leaf lists at $29,010.

The Prius has a city-highway combined efficiency of 50 miles per gallon. For the base-case analysis, let’s assume a gas price at $3.00 per gallon. This will result in a mileage efficiency of 6 ¢/mile.

The Leaf has an efficiency of 5.4 miles/kWh.[1] For base-case analysis, let’s assume electricity supply at a price of 12 ¢/kWh. This will result in a mileage efficiency of 2.2222 ¢/mile.[2]

For simplicity of analysis, let’s assume the a driver who needs to drive 12,000 miles a year or 1,000 miles a month for work, school, and other transportation needs. Let’s further assume the driver faces an auto loan’s interest rate of 3% per year or .25% per month.

To do: We first perform a base-case analysis using the data provided or assumed so far.

Q1: Calculate the monthly cash flows for purchasing and operating the Prius for 10 years.                                                                                                                       (10%)

Q2: Calculate the monthly cash flows for purchasing and operating the Leaf for 10 years.                                                                                                                       (10%)

Q3: From the monthly cash flows in the previous two questions, derive the incremental cash flows of purchasing the more expensive Leaf over the less-expensive Prius for 10 years.                                                                                                                       (10%)

Q4: From the incremental cash flows established in Q3 above, find the following capital-budgeting measures.

i. undiscounted payback in years;                                                                             (5%)

ii. discounted payback in years;                                                                                (5%)

iii. net present value, NPV, in $;                                                                             (10%)

iv. internal rate of return, IRR, in %                                                                       (10%)

v. profitability index (practitioner’s version)                                                          (10%)

vi. modified internal rate of return, MIRR, in %. Use reinvestment rate of 1% per annum or .08333% per month.                                                                                           (10%)

[1]   We obtain the 5.4 miles per kWh statistic from http://insideevs.com/long-term-nissan-leaf-mileageusage-review-once-around-the-sun/.

[2] The 2.2222 cents per mile number is consistent with Sharon Terlep’s article in The Wall Street Journal, August 12, 2009, where she reported the Chevrolet Volt’s lithium-ion battery pack can deliver a range of 40 miles before it needs recharging at 88 cents per charge. The Leaf has a range of 84 miles per full charge. We did not choose the Volt because the Volt is not an all-electric car with its fossil-fuel internal combustion engine backup propulsion.

A manufacturing firm has a monthly production of units modeled by?(?, ?) = 50?0.7?0.3 where x is the number of units of labor and y is the number of units of capital.
The company has a budget of $75,000 per month for labor and capital. If each unit of labor costs $30 and each unit of capital costs $25, how much should the company spend on labor and materials in order to maximize their production?

Thank you for your time and help.

1. In the first set of experiments, you dissolve 1g yeast in either water, or 10% solutions of different sugars. At room temperature, you set up the eudiometers in parallel, with lots of air in each flask before you begin. These are the results. Plot them using the scatter plot function, set the Y intercept=0, and display the equations of the trendlines on the chart, with the title and axes carefully labeled. You can select/copy/paste the data shown in each table by clicking the little icon in the upper left hand corner or you may use the Excel spreadsheet provided on Canvas. Insert your graph below the data table and answer the following questions. For all of the eudiometer experiments the CO₂ is measured in cubic centimeters or milliliters of displacement (of the colored water).

a) Which of the sugars are being used for cellular respiration by yeast at room temperature?

b) What is the rate of CO₂ production for glucose in this experiment?

c) Explain why yeast might not be able to use the other sugars for cellular respiration.

d) Consider the molecular structures of glucose and maltose. How might these results differ if you used 1M solutions instead of 10% solutions?

Create a Matlab program to load in the attached file File_Q5_Use.csv. You will first need to click on the link to open it, then save it as a .csv file in the directory you are using in your Matlab programs before you can load it in to Matlab.

It has 2 columns, the first column is the x values, the second column is the y values. Set Figure (1). Plot the points using red stars and a blue line with a title of 'Original Points' and get a general idea of what the degree of the polynomial is. It might be easier to split the matrix into 2 vectors x_vec and y_vec.

From the graph - where approximately are the real zeros of this polynomial? Does this polynomial appear to be ODD or EVEN. ? Answer the questions in the %RESULTS.  

After this plot, set Figure (2) to get a different Figure window open but so that the old figure window does not close.

Next, use POLYFIT to find the polynomial that fits the data [Hint: it is less than degree 8 and more than degree 1]. Use a FOR loop to cycle through the from n = 2:1:7 and do the following on each loop:

a. Find using POLYFIT, the polynomial for each degree of n. Do NOT suppress the values of the coefficients returned by each pass through the FOR loop.  

b. Using SUBPLOT where n is the location, plot on the same graph, the original points using red stars and the polynomial created by POLYFIT using a range of [-3:0.1:3] using a blue line. Make a title for each subgraph showing the degree of the polynomial fitted.  

Based upon the 6 graphs, which do you think is the correct degree of the polynomial? Answer in %RESULTS.

The basis for this polynomial was: 2x^5 - 3x^4 + 2x^3 -3x^2 - 144x + 216 = 0. Create a Figure 3 which plots the original points in red stars and points from this polynomial in a blue line for a range of [-3 : 0.1 : 3 ].  

Looking at the graphs, how many data points appear to be outliers, i.e. they probably should not be used in the graph? Answer in %RESULTS.

Looking at the graphs, the plots for degree 5, 6, 7 all appear to be almost the same. Switch to full screen to examine Figure 2. Remembering that the line of best fit passes through as many points as possible and minimizes the distances between the line and the points, can you determine by eye which degree of 5, 6, or 7 would be best?
