<span> see how you got 80%... but that was the amount paid.. they paid 80% for it, 20% is the percent that they didnt have to pay since it was on sale. what i would do is: </span> <span>40-32= 8. </span> <span>8/40= 0.2 </span> <span>20% </span>
<span>it is 8/40 because those are the 8 dollars that you didnt have to pay out of the 40. </span>
