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
