Derek will pay $625.25 less than the original prize
<u>Step-by-step explanation:</u>
The selling price of the computer=$610
The selling prize is 1/5 of its original prize
Derek has a 10% off coupon
Let the original prize of the computer=x
selling prize=x-x/5
4x/5=610
4x=3050
x=3050/4=762.5

the difference in the original prize and the prize at which Derek bought the computer=x-9x/50
=41x/50

Derek will pay $625.25 less than the original price for the computer.
