Your food bill at a restaurant is $30. You leave a 20% tip. The sales tax is 6%. What is the total cost of the meal?
ohaa [14]
The total cost of the meal is $37.80

Given:
Food bill = $30
tip = 20%
sales tax = 6%

Tip and sales tax must be based on the food bill.

Tip = $30 x 20% = $6
Sales Tax = $30 x 6% = $1.80

Food bill :   30.00
Tip               6.00
Sales tax  <u>   1.80</u>
Total cost 37.80
