Nowadays it is very important to reduce one's carbon footprint" (how much carbon we produce in our daily lifestyles). Minimizing the use of fossil fuels and instead resorting to renewable sources of energy (eg. solar energy) are vital to a "sustainable" lifestyle and a lower carbon footprint. Let's consider solar panels that prewarm the water fed to a conventional home water heater The solar panels have an installed cost of $3,700, and they reduce the homeowner's energy bill by $581 per year. The residual value of the solar panels is $703 at the end of their 12-year life What is the annual IRR of this investment? Use the trial-and-error method starting with an initial guess of 14%. (a) The annual IRR of this investment is %. (Round to two decimal places.) (b) If the homeowner's MARR is 14%, is the investment economical? PENA OA. Yes OB. No II

The owner of Barb’s Burgers has suggested the firm should invest in more moderntechnology and created a list of potential changes she thinks may be helpful as aninvestment. She has asked you to analyze the four potential choices and comment onwhat this would change in terms of cost:  Allow Barb’s Burgers to be delivered via the pre-existing food delivery systems.For example, allow people from Doordash/Uber Eats to pick-up orders and deliverthem. This would require the firm to make some minor changes and result in fewerparking spaces for customers dining at the restaurant. • Question: Argue how each of these is likely to change the cost of the firm once implemented (i.e. are any of these a fixed cost or a variable cost). How this adjust the amount of labour and/or capital currently necessary for the firm? Would the technology be a general technology, labour-saving, or capital-saving? Also mention the parking space.

You are considering adding a new software title to those published by your highly successful software company. If you add the new product, it will use capacity on your disk duplicating machines that you had planned on using for your flagship product, “Battlin’ Bobby.” You had planned on using the unused capacity to start selling “BB” on the West coast in two years. You would eventually have had to purchase additional duplicating machines 10 years from today, but using the capacity for your new product will require moving this purchase up to 2 years from today. If the new machines will cost $113,000 and can be expensed under Section 179, your marginal tax rate is 21 percent, and your cost of capital is 14 percent, what is the opportunity cost associated with using the unused capacity for the new product? (Negative amount should be indicated by a minus sign. Do not round intermediate calculations. Round your answer to 2 decimal places.)

Suppose you want to buy a Tesla Model S, the world's leading all-electric, zero-emission car that has a 265-mile range and can be recharged in three hours. The Tesla Model S Performance model has a list price of $87,500. However, you want several options (Performance Plus Package, red multicoat armor paint, Tech Package, Sound Studio Package, home charging station, performance wheels, and others) that will cost $17,500. An extended warranty will add an additional $5,000. However, if you put $50,000 down now and finance the balance over the next year, you will receive a dealer rebate of $5,000 off the list price. The dealer will give you a $7,000 trade-in allowance for your 2010 Honda Civic DX four-door sedan. In addition, you will have to pay a state sales tax of $10,000, an auto registration fee of $1,000 to the state, and a $1,000 destination charge to ship and prep the car. But because the Tesla Model S is an alternative energy vehicle, you qualify for a $2,500 state rebate and a…
