Question

A bill at a restaurant is $60. A 15% tip is left for the server. What is the total cost of the bill?

Answer 1

Answer:

$64

Step-by-step explanation:

The cost of food ($60) leads to a 15% tip.  The tip amount is calculated as follows:  0.15($60) = $4.

Adding the food cost and the tip amounts, we get $64, the total cost of the meal.

A faster approach would be to combine 1($60) + 0.15($60) into an expression of a single term:  (1 + 0.15)($60 = 1.15($60) = $64.
