Question

Antoine and Tess have a disagreement over how to compute a 15% gratuity on $46.00. Tess says, “It is easy to find 10% of 46 by moving the decimal point one place to the left to get $4.60. Do that twice. Then add the two amounts to get $4.60 + $4.60 = $9.20 for the 15% gratuity.”

Answer 1

Answer:Tess 20%

Explanation:

Answer 2

Tess is correct about figuring 10% but he added 2 of them together which is like adding 10% +10% which is 20% not 15%.

he should have taken 1/2 of the 4.60 for 5% since 5 is half of 10

half of 4.60 = 2.30

then add that to the 4.60

4.60 +2.30 = 6.90 is 15%
