1 ÷ 4 = 0.25
Next, is to raise the first answer gotten to the power of second.
1. 538 ^ 0.25 = 1.113625

The computation is shown below:
a. For the maximum amount that spend each month on mortgage payment is
= Gross annual income ÷ total number of months in a year × mortgage payment percentage
= $39,600 ÷ 12 months × 28%
= $924
b. . For the maximum amount that spend each month on total credit obligatons
= Gross annual income ÷ total number of months in a year × mortgage payment percentage
= $39,600 ÷ 12 months × 36%
= $1,188
c. Now the maximum amount spend for all other debt is
For monthly mortgage

= $646.8
And, for mortgage debt
= $1,188 × 70%
= $831.60
