Marcia is at a store with a 20% off sale. She also has a coupon for an additional 10% off the sale price. Prove or disprove the following statement: A 20% discount on the original price of an item, followed by the use of a 10% off coupon, results in a total discount of 30%.
With explaination pls ill brainliest someone who helps.

Answer

Disprove. If there is a item that is $100 it will become $80 from the sale. and thenyou have a 10% coupon, which 10% of 80 is 8. There for the item will cost $72 which is not 30%

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42

c: y > - 1/6x + 1

step-by-step explanation:

dashed line - meaning this < or > also not equal

solid line - meaning this < or > also equal

your answer is c because y > means up & it's shaded up, but y < means down

hope this ! : )
