Question

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

for dinner.

Answer 1

Answer: $79.12

Explanation:

`$$5 peopleeach order is worth \$12.80$$\begin{aligned}\therefore \text { Total bill } &=12.80 * 5 \\&=64 \$\end{aligned}$$`

`${Tax}: 7.5 \%$$\therefore$ Bill after tax$$\begin{aligned}&=64\left((100+7.5)/(100)\right) \\&=64(1.075) \\&\text{Bill \ with \ tax}=68.8 \$$\end{aligned}$$`

`$$Gratuity$=15 \%$ of bill with tax$$\begin{aligned}\therefore \text { Gratuity} &=0.15 * 68.8 \\&=10.32 \$\end{aligned}$$$\therefore$ Ended up paying a total of $=68.8+10.32$$$\ \ \ \ \ \ \ \ \ \ =\$79.12 $$`
