Answer 2

Answer:

A is correct

Step-by-step explanation:

Marshall bought some pet supplies for $15

The sales tax was 6%

Expression: 1.06(15)

Cost of pet = $15

Sale tax = 6% of 15

             = 0.06×15

Total cost after sale tax = 15 + 0.06×15

Take out 15 common = (1+0.06)15

The given expression is equivalent to (1+0.06)15

1.06(15) = (1+0.06)15

Using (1+0.06)15 to find total cost.
