Answer:
$107.50
Explanation:
Take that 25% and move the decimal point two spaces to the left. This will turn that 25% into .25
Now multiple that .25 times the $86 dollars.
That will give you the decimal 21.5, but since this is money, you would add a zero at the end to say that its fifty cents, giving you $21.50
You add that $21.50 to the $86 dollars you originally had which will give you the final answer of $107.50
Hope this helps
