Question

The cost of a ticket t to a concert with a 3% sales tax can be represented by the expression t + 0.03t. Simplify the expression. Then determine the total cost after the sales tax if the original price is $72.

Answer 1

T + 0.03t......simplified = 1.03t....with t being the original price

original price is 72....
so the total cost (including tax) is : 
1.03t...when t = 72
1.03(72) = 74.16 <==
