After eating at your favorite restaurant, you know that the bill before tax is $52.60 and that the sales tax rate is 8%. You decide to leave a 20% tip for the waiter based on the pre-tax amount. How much should you leave the waiter? How much will the total bill be, including tax and tip?

Step-by-step explanation:

After eating at your favorite restaurant,you know that the bill before tax is $52.60 and that the sales tax rate is 8%. This means that the amount of sales tax that you would pay is

8/100 × 52.6 = $4.208

You decide to leave a 20% tip for the waiter based on the pre-tax amount. This means that the amount you would leave as tip for the waiter is

20/100 × 52.6 = $10.52

The total amount that you would pay is

52.6 + 4.208 + 10.52 = $67.328

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius
