Step-by-step explanation:

Mavis charged $12 an hour to babysit, so her earnings for h hours would be 12h. She spent $3 on gas, which means her total earnings for the night would be 12h - 3. Finally, she deposited $45 into her account, so we can set up the equation as:

12h - 3 = 45

12h = 48

h = 4
