Ok, so you would use the simple interest equation, I=PRT where you are solving for I (interest). So, you would solve using P=3700, R= .05(percent in decimal form) and T=7 years. Multiply that all together and you answer would be $1295. But, that is just the interest so in order to get the total repayment you must add that number to 3700. So the answer would be D, $4995
