Answer:

$10,390.96

Explanation:

The formula for the principal amount is

P = A (1 - (1-r)^n / r)

From the given data, A = 100

r =  10 / 100 * 12 = 10 / 1200 = 0.0083

n= 20 * 12 = 240

Now substitute this data in the formula

P = 100 ( 1 - (1 + 0.0083)^-240 / 0.0083)

P = 100 ( 1 - (1/7.27016) / 0.0083)

P = 100 ( 1 - 0.13755 / 0.0083)

P = 100 ( 0.86245 / 0.0083)

P = 100 * 103.90964

P = $10,390.964

P = $10,390.96

The maximum amount that Fred can afford to borrow if the bank charges interest at an annual rate of 10 percent, compounded monthly is $10,390.96
