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?

What is the question being asked?

How much money will each charity receive?

How many charities can Katye donate to?

How much money will Katye give to the charities in all?

How much money will Katye have left after buying the book and making donations?

Answer 1

You would have to solve it like an equation, which would be 100 = 10x + 23, which represents the problem situation. Then you would solve algebraically, then you would see that you can only give to 7 charities with a remainder of 7 dollars left, after the books and donations.

Answer 2

Katie will have left $7 with her after donating to 7 charities.

Explanation:

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.

After buying a book, amount left with her =
`100-23=77` dollars

As she wants to donate $10 to each charity, that means she can donate to
`(77)/(10)=7.7` rounded to 7 charities.

She will have left
`77-(7*10)=7` dollars

So, Katie will have left $7 with her after donating to 7 charities.
