37+37+37+37=148 all you have to do is add 37 together four times
You would multiply the sales regular price by the percent and then subtract your answer from the regular sale price. For example, if something cost $499 and the sales price was 15% off, you would multiply 499 by 0.15 and then you would get 74.85.
You must perform some cancellations to arrive at the final answer. I hope this helps
