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

you cant answer this dummy

step-by-step explanation:

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice
