You purchase a car using a $20,000 loan with a 5% simple interest rate.
(a) suppose you pay the loan off after 4 years. how much interest do you pay on your loan? show your work.
(b) suppose you pay the loan off after 2 years. how much interest do you save by paying the loan off sooner? show your work.

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)
