Question

Caleb was out at a restaurant for dinner when the bill came. His dinner came to $21. He wanted to leave a 31% tip. How much was his meal plus the tip, before tax, in dollars and cents?

Answer 1

$27.51

Explanation:

To calculate the amount of the tip, first convert the 31% into a decimal.

31 ÷ 100 = 0.31

multiply the total amount of the dinner by 0.31 to calculate the price of the tip:

21 × 0.31 = $6.51

therefore, the tip was $6.51

add this onto the originial $21 to calculate the full amount before tax:

21 + 6.51 = 27.51

therefore, the total amount due was $27.51
