You have recently assumed the role of CFO at your company. The company's CEO is looking to expand its operations by investing in new property, plant, and equipment. You are asked to do some capital budgeting analysis that will determine whether the company should invest in these new plant assets.
-The firm is looking to expand its operations by 10% of the firm's net property, plant, and equipment= 2018 = $61,797 million, increase 10% = $6,179.7 million to total $67,976.7 million
-The estimated life of this new property, plant, and equipment will be 12 years. The salvage value of the equipment will be 5% of the cost.
-EBIT = 18% of the project's cost
-The hurdle rate for this project will be the WACC = 8.5%
Calculate the discounted payback period.

A firm is considering replacing the existing industrial air conditioning unit. They will pick one of two units. The first, the AC360, costs $26,161.00 to install, $5,148.00 to operate per year for 7 years at which time it will be sold for $6,874.00. The second, RayCool 8, costs $41,347.00 to install, $2,073.00 to operate per year for 5 years at which time it will be sold for $9,004.00. The firm’s cost of capital is 6.50%. What is the equivalent annual cost of the AC360? Assume that there are no taxes.
Answer format: Currency: Round to: 2 decimal places.

2. Salsa Aguilar, a small startup business located in Pennsylvania, produces salsas that are sold through Heisler’s Market, a local grocery store located in McMurray, PA. Salsa Aguilar makes two types of products: Original Salsa and Fuego Salsa. Essentially, the two products have different blends of whole tomatoes, tomato sauce, and chopped vegetables. The Original Salsa is a blend of 50% whole tomatoes, 40% tomato sauce, and 10% chopped onions and jalapenos along with a proprietary spice blend. The Fuego Salsa, has a thicker and chunkier consistency, consists of 70% whole tomatoes, 10% tomato sauce, and 20% chopped onions and jalapenos, along with a proprietary spice blend. Each jar of salsa produced weighs 12 ounces. For the current production period, Salsa Aguilar can purchase up to 200 pounds of whole tomatoes, 150 pounds of tomato sauce, and 85 pounds of chopped onions and jalapenos; the price per pound for these ingredients is $1.00, $0.75, and $0.60, respectively. The cost of the spices and the other ingredients is approximately $0.15 per jar. Salsa Aguilar buys empty glass jars for $0.03 each and labeling and filling costs are estimated to be $0.02 for each jar of salsa produced. Salsa Aguilar’s contract with Heisler’s Market results in sales profit of $3.00 for each jar of Original Salsa and $3.25 for each jar of Fuego Salsa.
| Ingredient | |||||
| Amount | Price | Cost by jar | |||
| Product mix 12 oz jars | Purchased | per lb | TOTAL | size | |
| Type of Constraint | O F | 1lb = 16 ounces | |||
| Whole tomatoes | 50% 70% | 200 | $1.00 | $200.00 | $266.67 |
| Tomato Sauce | 40% 10% | 150 | $0.75 | $112.50 | $150.00 |
| Onion & Jalapeno | 10% 20% | 85 | $0.60 | $51.00 | $68.00 |
Letting
O = number of jars of Original Salsa sold
F = number of jars of Fuego Salsa sold
Leads to the formulation of the linear program as follows. The RHS ranges are simply the total ounces of each ingredient and the LHS ranges reflect the quantity in ounces of each ingredient that goes into each jar. Note that the pricing information here is not relevant to our analysis, since we are considering only the net profit for each jar:
Max 3O + 3.25F
s.t.
6O + 8F ≤ 3200 Whole tomatoes
5O + 1F ≤ 2400 Tomato Sauce
1O + 2F ≤ 1360 Chopped Onions and jalapenos
O, F ≥ 0

The Rosetta space probe has a mass of 1200 kg. On November 12th 2014,Rosetta landed on Comet 67P/C-G which has a mass of M= 1×10 ^18 kg. The instant before landing was initiated, scientists found Rosetta’s relative (to the comet) position and velocity to be: r=〈3×10^3,0,5×10^3m v=〈−1×10^2,2×10^2,0〉m/s Calculate the (approximate) momentum and position of the space probe 100 seconds later. Start from a fundamental principle and show all steps in your work. Express your final answer as three-component vectors.
