I have a Hyundai with mpg of 20 and I plan to keep it for the next 7 years. I drive 10,000 miles a year, the price of gas for 2020 is $3, and it will increase with the same pace as inflation of 2%. (Hint 1: you don't need to calculate gas price for each year to account for its price increase - only adjusting interest rate for inflation accounts for the price increase). Nominal interest rate is 8%. For simplicity, we assume gas prices don't fluctuate and I pay for all the gas I use during the year at the end of that year. (Hint 2: this means that you can calculate inflation adjusted net present value of my gas expenditure.) Imagine I could replace my Hyundai with a Tesla Model 3 for free. Tesla drives for 250 miles on a single charge. A single charge for me requires 50 kwh of electricity at a cost of 13 cents per kwh with charging efficiency of 85%. (Hint 2: you can calculate cost of a single charge by multiplying battery capacity by the cost of each unit divided by the charging efficiency.) Similar to gas, assume electricity cost also does not fluctuate, increases by inflation, and I pay for it at the end of each year. What is the inflation-adjusted NPV of my energy savings after I switch to Tesla? Round your answer to the nearest dollar and enter without $ sign. For example, enter 743 for $742.76
