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.

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.
