Answer:
Maximum initial purchase that Carla can buy on credit is $1455.08
Explanation:
Formula = M = [P (1 + r)^n * r] / [(1 + r)^n - 1]
$70 = P [(1 + 0.142/12)^24 * 0.142/12 ] / [(1 + 0.142/12)^24 - 1]
= $70 = P (1.326209535) * 0.142/12 / 0.326209535
= $70 = P * 0.0156934795 / 0.326209535
= P = $1455.08
So, the maximum initial purchase that Carla can buy on credit = $1455.08
