Use S.O.L.V.E.D method

Answer 1

It's simple, first you have to read the text, let's start.

She arrives with x

Jenny bought 7 T-shirts

x-7*price, so x-7*9.95

The cashier charged her an additional.


`x-7*9.95-13.07`

Then left for her 7.28

therefore


`x-7*9.95-13.07=7.28`


`x-69.65-13.07=7.28`


`x-82.72=7.28`


`x=7.28+82.72`


`\boxed{\boxed{x=\$90.00}}`

She started with $90.00
