Frank purchased a boat for $7,525. He made a down payment of $475. He applied for a six-year installment loan with an interest rate of 8.4% in the amount of $7,050. What is the total cost of the boat after six years?

OpenStudy (phi):

if this is simple interest, the total interest is I= P*r*t where P is the amount of the loan, r is the rate (as a decimal), and t is the time

OpenStudy (phi):

So the first step is assign numbers (from the problem) to the variables P, r and t
