Question

Neil took his family of five out to dinner at HogTastic Pit BBQ. They all ordered the buffet and drink at $12.80 each. Neil left a 15% gratuity for the waitress on the after-tax bill. Based on a tax rate of 7.5%, Neil ended up paying a total of $______ for dinner.

Answer 1

A quick answer:

12.80x 5 = 64

64 x 1.075(tax plus the original bill before tax)= 68.8

68.8 x 1.15(gratuity plus the bill after tax) = $79.12

Neil ended up paying $79.12 for dinner

Answer 2

This question makes me hungry! :-p

5 buffets & drinks purchased,

So 5*12.80 = 64.00. (food cost)

Tax on purchase is 7.5% or .075

Tax = .075 * 64 = 4.80

Food + tax = 64 + 4.80 = $68.80

Next, need to figure the gratuity

It is 15% or .15

.15*(68.80) = $10.32

I'll leave it to you to finish...
