Answer:
If Maggie wants to make $105 dollars this weekend to afford her bag, she will have to babysit at least 7 hours and at most 13 hours.
Explanation:
We take the amount of money Maggie wants, which is 105$, and we divide it by the amount of money Maggie makes per hour, which is 15$.
105 / 15 is 7.
Then we take the max amount of money Maggie wants to make and divide it by 15.
195 / 15 is 13.
So therefore the answer is 7 to 13 hours.
