Answer: HERES YOUR HURRIED ANSWER!
Let's start by finding the total amount of money that Katye will donate to the local charities.
If she donates $10 to each charity, and she donates to as many charities as possible, then we can use division to find the number of charities:
Number of charities = (total cash - cost of book) ÷ donation amount
Number of charities = (100 - 23) ÷ 10
Number of charities = 7
So Katye can donate to 7 charities
The total amount she will donate is:
Total donation = number of charities × donation amount
Total donation = 7 × 10
Total donation = $70
To find out how much money Katye will have left over, we can subtract the cost of the book and the total donation from the total amount of cash:
Leftover money = total cash - cost of book - total donation
Leftover money = 100 - 23 - 70
Leftover money = $7
Therefore, Katye will have $7 left over after buying the book and donating to as many local charities as possible
