Question

Consider this math problem that Maureen had and answer both questions.

Maureen went out to eat with friends and decided to pay the entire bill. The total
of the bill came to $102 and she figured that she would leave a 15% tip. So, she
took 15% of $102 by multiplying 1.5 by $102 and left a tip of $153.

a. What mistake did Maureen make?

b. What is 15% of $102? Show the correct expression (Your work) and state
the solution correctly (example: $10.70)

Answer 1

a. The mistake that Maureen made is that she miscalculated the amount of the tip. She multiplied $102 by 1.5 instead of multiplying it by 0.15 to find 15% of the bill.

b. To find 15% of $102, we need to multiply $102 by 0.15. The correct expression is:

$102 * 0.15 = $15.30

Therefore, 15% of $102 is $15.30.
