You go to see you go Joey Bones, a local loan shark, to inquire about the interest rate on loans. You are told the interest will be a 1 percent discount loan. If you borrow $2,100 for one week, the net interest will owe will be: $2,100(1 + .01)7 $2,100 = $151.48. Since this is a discount loan, you will receive $2,100 151.48 = $1,948.52 today. To help Joey on his bookkeeping, he will require you to make seven daily payments of $300 to repay the loan. If you are brave enough to ask, what APR will Joey say you are paying? What is the EAR you are paying? Assume 365 days in a year.
