A homeowner installed a new swimming pool for $8500. He paid 8% down and then paid 36 monthly payments of $243.07. Determine the APR of the loan to the nearest one-half of a percent.
Po =(1-0.08) * 8500 = $7820.
P = 243.07/mo. * 36mo. = $8750.52
P = Po + Po*r*t = 8750.52
7820 + 7820*r*3 = 8750.52
7820 + 23,460r = 8750.52
23,460r = 8750.52-7820 = 930.52
r = 3.97% or 4.0% = APR.
P = 243.07/mo. * 36mo. = $8750.52
P = Po + Po*r*t = 8750.52
7820 + 7820*r*3 = 8750.52
7820 + 23,460r = 8750.52
23,460r = 8750.52-7820 = 930.52
r = 3.97% or 4.0% = APR.
