Okay, so first, Kate buys one book that costs $23. Let's subtract 100 by 23, which is 77. Next, she wants to donate $10 to several charities. If she is feeling extra generous and donates to as many charities as possible, she will donate to seven charities with seven dollars left over. How would I figure this? Well, divide 77 (the sum left over after purchasing the book) by 10. That equals seven (there are seven tens in 70) with a remainder of 7 (she has seven dollars left over, since she cannot donate $7, she can only donate in tens). Hope this helps. 

Answer:

Subtract 23 from 100 to find the amount available to donate.

Divide the amount available by 10 and round down to find the number of charities.

Multiply the number of charities by 10 to find the total charitable donation.

Subtract the total charitable donation from the amount available to donate.
