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

Algebra 
Ms. Sue
3.5h = 15
Solve for h

so would it be 15/3.5
so 4 hours?

Ms. Sue
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

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.
