Question

A man’s suit was on sale for 15% off the regular price. The sale price was $216.75. What was the regular price?

Answer 1

255 must be the one

Answer 2

216.75 is the sale price after 15% off. that means you will have to multiply 15% times 216.75.  216.75*0.15 would be $32.51. 
you need to add them together to get the original price so 216.75+32.51 equal 249.26
