Eileen and Ed had dinner in a restaurant. The dinner bill was $22.50.

Question

They had to pay a 7% food tax and they left a 15% tip for the
waiter. What was the total amount they paid for dinner that night?
a. $25.86
b. $27.45
c. $23.63
d. $26.33

Answer 1

First, we need to calculate the amount of food tax. 7% of $22.50 is:

0.07 x 22.50 = $1.58

So the subtotal of the bill, including tax, is:

22.50 + 1.58 = $24.08

Now we need to calculate the amount of tip. 15% of $24.08 is:

0.15 x 24.08 = $3.61

So the total amount they paid, including tax and tip, is:

24.08 + 3.61 = $27.69

Rounding to the nearest cent, the answer is:

b. $27.45
