Jenna ordered four pizzas for $8.55 each, including tax. If she wanted to give a 15% tip, what would her total bill be?

Given:

Cost of each pizza including tax = $8.55

Number of pizzas = 4

Tip = 15%

To find:

Her total bill.

Solution:

We have,

Cost of 1 pizza including tax = $8.55

Cost of 4 pizza including tax =

                                                =

It is given that she wanted to give a 15% tip. So, tip is 15% of $34.2.

Thus, the amount of tip is $5.13.

Now the total amount of bill is:

Therefore, the total amount of bill is $39.33.
