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 babysitting. HELP PLEASE

3.5h = M

from this, how do you figure out how long it would take him to make 15 dollars?

Algebra  Ms. Sue, Wednesday, November 17, 2010 at 6:10pm
3.5h = 15
Solve for h 
Algebra  Johnny, Wednesday, November 17, 2010 at 6:10pm
so would it be 15/3.5
so 4 hours?

It would take more than 4 hours.
After four hours he'd only have $14.00.

then what do you do to get the answer?

Algebra  Ms. Sue, Wednesday, November 17, 2010 at 6:30pm
Divide 15 by 3.5

but that's what i did and you said it was wrong

Algebra  Ms. Sue, Wednesday, November 17, 2010 at 6:45pm
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.
