You are planning to buy a car on credit. The car costs $30,000 today. The dealer offers financing (a car loan) for 2 years at an APR of 12% compounded monthly. The first monthly payment is a month from today. How much is the monthly payment under the financing (car loan) if you purchase the car on credit today? For your answer round to the nearest dollar, do not enter the dollar (\$) sign, and DO NOT use commas for the thousands. For example, if you obtained $1,240.75 then enter 1241 (some problems might let you use commas though). (Estimated time allowance: 15 minutes) Given an interest rate of 10 percent per year, what is the value at date t=4 (the end of year 4 ) of a perpetual stream of $300 annual payments that begins at date t=13 (the end of year 13 ). For your answer round to the nearest dollar, do not enter the dollar (\$) sign, DO NOT use commas for the thousands. For example, if you obtained $1,240.75 then enter 1241 (some problems might let you use commas though)
