Katye received 15 gifts and a total of $100 in cash for her birthday. She buys one book that costs $23, and she wants to donate $10 to each of several local charities. How much money will Katye have left over if she donates to as many charities as possible?

Use the equation:
10x + 23 = 100
Subtract 23 from each side:
10x = 77
EVENLY divide by 10, leaving a remainder:
x = 7 charities and $7 left over

Hope this helps!! :)
She will have 7 dollars left.
You take 100 and - 23.
You get 77, then you keep subtracting 10 until you can't anymore. So you will be left with 7 dollars
