Answer 2

Problem:
Sam is going to buy a shirt for $15.00 and a pair of pants for $25.00. She has to pay 7% sales tax. If Sam pays with $50 bill,how much change will she get back?

Here's how I would approach it.
The total purchase is $15+$25, or $40.
She'll have to pay 7% tax on top of that, so the total is $40 X (1.07)
that can be tricky, just remember that 0.07 is like 7%.
Once you find that total amount, subtract it from $50 to determine the change.

Hope that helps!
