Hi there!
First we need to calculate how much the 3 T-shirts cost and subtract that from the amount she paid to find the change.
First, we multiply to find the coats of the T-shirts.
3 × 8 = 24
Now, we subtract 24 from 50.
50 - 24 = 26
So, she got $26 of change.
Hope this helps!
Can you post the rest of the info? x
