Solving for R

Where Fa is computed by

We'll use the provided values but we need to convert them first to monthly payments




Thus, each payment is


The correct equation to solve for x would be 12x - 19 + 4x + 1 = 180

12.80+3.42= 16.22
16.22-9.70= 6.52 that's your answer
for estimating round both the price of shoes and the percentage to round numbers
97.65 is close to 100, so use 100 for the price of shoes
68% is close to 70 so use 70%
then multiply 100 by 70 %,
100 *70% = 70 dollars
so Isaac would pay around 70 dollars
