PLZ Help me Elizabeth wants to buy 15 pizzas that are $8 each and will also be charged 7% in sales tax. What will Elizabeth's total bill be?

$128.40

Step-by-step explanation:

Find the total cost of the pizza before tax.

15 × 8 = 120

Set up a proportion to find the tax.
7/100 = x/120

Cross multiply

840 = 100x

Divide both sides by 100

Tax = $8.40

$120 + $8.40 = $128.40

I hope this helped and please mark me as brainliest!

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.

the answer will be b x² +x-1
