Answer:
7 - 13 hours
Explanation:
This is just a common word problem.
Maggie gets charged $15 an hour and wants at least $105 and under $195
105 divided by 15 is 7 hours. 195 divided by 15 is 13 hours
The answer is she can babysit for 7 - 13 hours so she can make enough money for the bag she wants without having to pay taxes for her earnings.
