Answer 1

To find the total cost of Rosa's meal, calculate the sales tax and the tip, and then add them to the cost of the meal. The total cost of Rosa's meal is $4.77. The correct answer is C. $5.37.

Step-by-step explanation:

To find the total cost of Rosa's meal, we need to calculate the sales tax and the tip, and then add them to the cost of the meal.

First, let's find the sales tax. Since the sales tax rate is 8%, we multiply the cost of the meal by 0.08 to get:

$3.88 × 0.08 = $0.3104

Next, let's calculate the tip. The tip amount is 15% of the cost of the meal, so we multiply the cost of the meal by 0.15 to get:

$3.88 × 0.15 = $0.582

Finally, we add the cost of the meal, the sales tax, and the tip:

$3.88 + $0.3104 + $0.582 = $4.7724

Rounding to the nearest cent, the total cost of Rosa's meal is $4.77. Therefore, the correct answer is C. $5.37.
