Your dinner bill is $25 before tax. the tax rate is 8%. you decide to give the waiter 10% tip based on your pre-tax bill. what is the total amount of cash you should pay?

$29.50

Step-by-step explanation:

First we need to find the tip

tip = pre tax bill * 10 %

tip = 25 * .10

tip =2.5

Next we need to find the tax

tax = pre tax bill * 8%

tax = 25 * .08

tax =2

Final bill = pre tax bill + tax + tip

Final bill = 25 + 2 + 2.5

              =29.50
