a coat cost 152.98 it go's on sale for 25% off then you have to and the sale tax of 8 1/4 then you have to round it off to the nearest dollar.zabon

Answer 1

100% = 1

25% = 0.25

8 and 1/4 percent = 8.25% = 0.0825

100% - 25% = 75% = 0.75 = 1 - 0.25

100% + 8.25% = 108.25% = 1.0825 = 1 + 0.0825

152.98 * 0.75 * 1.0825 = 124.20
