Asked by Johnny

Juan charges $3.50 per hour for babysitting. Write a rule to describe the amount of money (M) earned is a function of the number of hours (h) spent baby-sitting. HELP PLEASE
Answered by Ms. Sue
3.5h = M

Answered by Johnny
from this, how do you figure out how long it would take him to make 15 dollars?
Answered by Ms. Sue
3.5h = 15

Solve for h

Answered by Johnny
so would it be 15/3.5
so 4 hours?
Answered by Ms. Sue
It would take more than 4 hours.

After four hours he'd only have $14.00.



Answered by Johnny
then what do you do to get the answer?
Answered by Ms. Sue
Divide 15 by 3.5

Answered by Johnny
but that's what i did and you said it was wrong
Answered by Ms. Sue
15 / 3.5 = 4.28571429

You forgot the decimal places. It would take Juan about 4.3 hours or 4 hours and 18 minutes to earn $15.00.
