Suppose that in a given store, customers are willing to buy y pounds of coffee beans per day at $x per pound, as given by the price-demand equation y=10+(180/x) for 2 (is less than or equal to) x (is less than or equal to) 10.

a. Find y’ with appropriate units. Explain what the first derivative means in this situation by hand.

b. Find the demand and the instantaneous rate of change of demand with respect to price when the price is $5.

c. Use a table of values to sketch a well-labelled graph of this function between $2 and $10 per pound.

d. Does the rate of demand increase or decrease over time? Explain.

The cross-price elasticity between two products is estimated to be 3. If the price of the first product is decreased by 3.9%, demand for the second product will change by_____%.

Hint: Round to the second decimal. Answers are in percentages and can be positive or negative. If you calculate .0151 then input the answer as 1.51.

Assume that the price and income elasticities of demand for luxury cars are E_P = –0.52 and E_Y = 3.2 respectively. In the coming year, car prices are expected to decrease by 1.34 percent and income increases by 8.7 percent. Based on this information, sales of cars are expected to increase by_____%.

Hint: Round to the second decimal. Answers are in percentages, if you calculate .0151 then input the answer as 1.51.

JAVA for Dummies HELP

Problem Statement: Jeff Bezos has decided to have a party at his mansion, and he’s invited 50 couples. As the couples arrive at the mansion, they receive a ticket with a number (like at the deli counter), with the first couple receiving the tickets labeled 1 and 2, the second couple getting 3 and 4, and so on. Jeff has noticed in the past that when he throws parties, conversation groups most often occur in groups of 4 people. Being a nerd, he wonders: Exactly how many different conversation groups of 4 are possible at this party?

He writes himself a short Java program, and in minutes he has his answer….

(WRITE THIS PROGRAM)

(An important small hint – the person who has the ticket with a “1” on it can only (obviously) occur once in a given group – so, for example the grouping 1, 1, 2, 3 could NEVER occur!)

initialize a counter to 0;

--for each possible int value for personOne (starting at 1, ending at 100-3)

-----for each possible int value for personTwo (starting at personOne+1, ending at 100-2)

-------for each possible int value for personThree(starting at personTwo+1, ending at 100-1)

--------for each possible int value for personFour(staring at personThree+1, ending at 100)

increment the count output the result;

 A firm is considering renewing its equipment to meet increased demand for its product. The cost of equipment modifications is $ 1.88 million plus $ 111,000 in installation costs. The firm will depreciate the equipment modifications under​ MACRS, using a​ 5-year recovery period​. Additional sales revenue from the renewal should amount to $ 1.17 million per​ year, and additional operating expenses and other costs​ (excluding depreciation and​ interest) will amount to 40 % of the additional sales. The firm is subject to a tax rate of 40 %. ​(Note​: Answer the following questions for each of the next 6​ years.)

a. What incremental earnings before​ depreciation, interest, and taxes will result from the​ renewal?

b. What incremental net operating profits after taxes will result from the​ renewal?

c. What incremental operating cash inflows will result from the​ renewal?

P11–18 Operating cash flows: Expense reduction Miller Corporation is considering replacing a machine. The replacement will reduce operating expenses (i.e., increase earnings before interest, taxes, depreciation, and amortization) by $16,000 per year for each of the 5 years the new machine is expected to last. Although the old machine has zero book value, it can be used for 5 more years. The depreciable value of the new machine is $48,000. The firm will depreciate the machine under MACRS, using a 5-year recovery period (see Table 4.2 for the applicable depreciation percentages), and is subject to a 21% tax rate. Estimate the operating cash flows generated by the replacement. (Note: Be sure to consider the depreciation in year 6.)
