While on vacation in rockport, cole went out for a dinner that cost $30. if sales tax in rockport is 10% and cole left a 20% tip on $30, what was the total cost of his meal?

$39

Step-by-step explanation:

To calculate the total cost of his meal, add the subtotal ($30), the tax on subtotal ($30 X 10%) and the tip ($30 X 20%).

Convert all percentages to decimals to multiply.

Finding tax:

10% = 0.1

Tax = $30 X 0.1 = $3

Finding tip:

20% = 0.2

Tip = $30 X 0.2 = $6

Subtotal + Tax + Tip

= $30 + $3 + $6

= $39

The total cost of his meal was $39.
