You purchase a shirt for $8.50. there is a 6% sales tax. what will your total cost be?

The total cost and closest answer is $9.01

First, determine the 6% of the given base price, $8.50 by multiplying this base price to the decimal equivalent of 6%.
                          $8.50 x 0.06 = $0.51
Add this amount to the base. That is,
                             $8.50 + $0.51 = $9.01
Hence, the total cost would be $9.01.
