4 A store is having a 10% -off sale on all merchandise.

If Mai buys one item and saves $18, what was the original price of her purchase?

Step-by-step explanation:

If may buys an item that, after 10% sale, costs 18 dollars

let x be original price

discount is 10%x=0.10 x

x- 0.10x=18

0.90x=18

x=18/0.90=20

x=20

the answer is 14ft

step-by-step explanation:

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y
