Question

A restaurant customer left 3.50 as a tip. The tax on the meal was 7. What was the total cost of the meal?

Answer 1

To calculate the total cost of the meal, we need to add the cost of the meal, the sales tax, and the tip together. The cost of the meal before the sales tax was added is $50. Finally, by adding the cost of the meal, the sales tax, and the tip together, the total cost of the meal is $57.

Step-by-step explanation:

To find the total cost of the meal, we need to add the cost of the meal, the sales tax, and the tip together.

First, let's calculate the sales tax:

Sales tax amount = 7% of the cost of the meal

7% of the cost of the meal = (7/100) * Cost of the meal = 0.07 * Cost of the meal = 3.50

Therefore, the cost of the meal before the sales tax was added is: Cost of the meal = 3.50 / 0.07 = $50

Finally, to find the total cost of the meal, including the sales tax and the tip, we add the cost of the meal, the sales tax, and the tip:

Total cost of the meal = Cost of the meal + Sales tax + Tip = $50 + $3.50 + $3.50 = $57
