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.
