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

11 answers

3.5h = M
from this, how do you figure out how long it would take him to make 15 dollars?
3.5h = 15

Solve for h
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?
Divide 15 by 3.5
but that's what i did and you said it was wrong
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.
this questions confusing
ANSWER:
A.
M = 3.5h; about 4 hours

STEP BY STEP EXPLANATION:
The amount earned M is equal to the hourly rate times the number of hours h spent baby-sitting.

M=3.5h15=3.5h 4≈h

It will take Juan about 4 hours to earn $15.
