The answer is C $1,098.52...because I got it right
Principal (p) = $85600
Rate (r) = 11.5%
Time = 12 years
Interval = monthly = 12 months
Compound interest (A) = P * (1 + r/n)^nt
A = 85600 * [ 1 + (0.115 / 12)] ^ 12 * 12
A = 85600 * [1 + 0.009583]^144
A = 85600 * [1.009583]¹⁴⁴
A = 85600 * 3.95
A = $338120
She's supposed to pay $338120 compounded into (12months * 12 years) = 144 months
Every month she pays 338120 / 144 = $2348.05.
Every month she pays $2358.05
