Answer:

The file includes the input of your equation, comment if the equation you input is a mistake.
.8x125=100 your answer is 100
$18,617.75 is the answer
$87,525-$77,100=$10,425 (the amount over $77,100)
$10,425 x .28=$2,919 (the 28% taxed amount over $77,100)
$2,919+$15,698.75 (the already taxed amount in the chart)=$18,617.75
