1. Kim owns a Porsche and a Toyota. The Porsche has a fuel economy of 15 miles per gallon (mpg) and she plans to drive it 3,000 miles this year. The Toyota gets 30 miles per gallon and she plans to drive it 15,000 miles this year.
Suppose Kim can install a device that improves the fuel economy of any vehicle by 5 miles per gallon. However, she only has one of the devices. Which vehicle should she install it on if her goal is to minimize fuel consumption this year? Assume that the device does not hamper vehicle performance in any way.

- 1. Jack is considering selling his elliptical machine, which he never really used, is high quality, and has been taking up space in his spare bedroom. He lists it on Facebook Marketplace for "$1,200 or best offer" but in reality won't sell it for less than $1,000. Lina is looking to purchase a used elliptical machine. For a high-quality elliptical, she is willing to pay up to $1,300, and for a low-quality elliptical, she is willing to pay $600. Lina is risk neutral but she cannot tell if the elliptical machine is high quality or low quality. If she believes that 60% of used elliptical machines are high quality and 40% are low quality, what is the maximum price that Lina would be willing to pay? Would Jack agree to this price?arrow_forward3) Marco has $100 worth of grain in period 1 but gets no grain in period 2. Marco has two choices. He can store the grain that he does not consume in period 1. This results in a loss of 20% of the grain due to pests. Assume that with this option he will choose to consume 68 units of grain in period 1 and 26 units in period 2. Instead, Marco can sell the grain he does not consume in period 1 and lend the money from that sale to someone today at an interest rate of 10%. He can then use the repayment of that loan to buy gain in period 2. a) Based on this information, draw a diagram that outlines Marco's choices. Is he definitely better off once the opportunity to lend is available to him? b) Relative to his initial equilibrium point, does he unambiguously consume more in both periods once he can lend out the excess he does not consume in period 1? c) Now assume that Marco can sell any excess grain he doesn't consume in period 1 and invest the money he gets in a new type of risky activity.…arrow_forwardYou need to get gasoline for your car. You can drive ten miles (round trip) to a gas station on the outskirts of town and save 15 cents per gallon on the price of gasoline. If gasoline costs $3.55 per gallon and your car gets 37 miles per gallon for in-town driving, how many gallons of gasoline must you buy at the edge-of-town station to save enough on your fill up to pay for the cost to going to the station and back? Ignore the wear- and-tear cost of operating your car in this example. (Enter your answer as a number without the units of gallons.)arrow_forward

Usually, he buys 44 pizzas for $180$180 and spends the remaining $60$60 on 44 burgers. However, the price of 11 pizza has increased by $5$5; the price of a burger has not changed. Now, Jayden will buy only 33 pizzas per month.Calculate how many burgers Jayden can afford to buy if he still wants to spend all the money. If necessary, round any intermediate calculations to two decimal places. For your final answer, write the exact value; do not round.arrow_forwarddescribe new changes to kiwisaverarrow_forward

At every time step, there is a demand for energy in the home which is drawn from 0,1,2 units with equal probability independent of the demands in the previous time steps. At every point in time, you have to satisfy the demand either by discharging the needed energy from the battery or purchasing power from the grid (or a combination of the two). You could also choose to purchase power from the grid to charge your battery. The grid energy price is either H(igh) or L(ow) according to a Markov chain (Price moves from H to L with probability p, and from L to H with probability q). (a) Model the decision making as an infinite horizon MDP where the objective is to minimize the discounted cost of energy purchased over an infinite horizon. (b) Write down a policy a of your choosing. Perform two steps of the operator T, for your policy, followed by one step of T..arrow_forwardNonearrow_forward

Each month, the high-tech facility handles 10,000 claims, incurs $100,000 in fixed costs and $100,000 in variable costs. Each month, the low-tech facility handles 2,000 claims, incurs $16,000 in fixed costs and $24,000 in variable costs.
