Question

Bob is taking Jill out to dinner. Their bill was $27.50. If Bob spent a total of $32.45 including the tip what was the

percentage of the tip?

Answer 1

Explanation:

100% = $27.50

1% = 100%/100 = $27.50/100 = $0.275

the extra amount paid (for the tip) was

$32.45 - $27.50 = $4.95

to know how many percent that is, we need to see how often 1% fits into that amount.

so,

4.95 / 0.275 = 18

therefore the tip was 18%.

FYI - in real life the tip percentage (and corresponding amount) is calculated based on the net bill (the amount before sales tax).

Answer 2

$4.95 to be exact. About 15%
