Question

Natsumi went on a business lunch. The pretax bill was $55.60. She decided

to leave a 15% tip. The sales tax rate is 8.25%. What was the final amount of
the bill?

Answer 1

8.25% of 55.60 = 4.58700

We round that number to 4.59

(I am assuming the tip is based on the amount of the pretax bill.)

15% of 55.60 = 8.34

So $55.60 + $4.59 + 8.34 = $68.53

The bill would be $68.53.
