Question

Darla’s dinner at a restaurant cost $23.18 before tip. She wants to leave a 20% tip. What is the total cost of the dinner after Darla adds the tip?

Answer 1

The correct answer is 23.18%

Answer 2

$27.816

Explanation:

First we have to find out what 20% of 23.18 is. Let x represent the amount of the tip.

(cross multiply)

20 = x

100 23.18

20 x 23.18 = 463.6

463.6 ÷ 100 = 4.636

x = $4.636

Now we add the amount of the tip to the original price of the dinner.

23.18 + 4.636 = 27.816

Therefore the total cost of the dinner including the tip is $27.816
