The expression P(1+r) represents the cost after sales tax is calculated of an item originally priced P and taxed by a rate of r.

If you expand the expression, which term expresses the additional amount that you have to pay in tax?


1


r


P


Pr

Answer 1

After expanding the expression by using distribution, you get P + Pr. Since r is the rate an item is taxed by, the term Pr expresses the additional amount that you have to pay in tax. Pr is the answer. I hope this helped!
