A. $85

B. $78

C. $67

D. $13

Answer 1

Answer: A

Explanation:

the total cost of their meal it usally means how much in total so we add 65+20 = 85

Answer 2

Answer: B, $78

Explanation:

If the tip is 20% of the dinner cost, then we have to first find what is 20% of 65.

20% x 65 = 13. So the tip for the dinner is 13 dollars.

Now we have to add it to the original dinner cost.

65 + 13 = 78.

Therefore, the total cost of their meal is 78 dollars. So the answer is B, $78!
