Question

you buy a skate board helmet for $22.26 which includes 6% sales tax. the helmet discounted 30% off the selling price. what is the original price?

Answer 1

whatever it was, you multiplied by \(1.06\) to increase by 6% and \(.7\) to decrease it by 30%
so you know
\[(1.06)(.7)P=22.26\] and you get to solve for \(P\)

Answer 2

thanks
