Answer:

Neil ended up paying a total of $79.12.

Step-by-step explanation:

Neil took his family of five out to dinner and they all ordered the buffet and drink at $12.80 each.

So, they are a total of 5 members who have total expenditure of (5 × 12.80) = $64.

If the tax rate is 7.5%, then the after-tax bill will be 64(1 + \frac{7.5}{100}) = 68.8 dollars.

Now, Neil left a 15% gratuity for the waitress on the after-tax bill.

Therefore, the final payment amount of Neil will be 68.8(1 + \frac{15}{100}) = 79.12 dollars.

So, Neil ended up paying a total of $79.12. (Answer)
