Each bottle of juice costs $3, so to find the total price of the bottles, you would have to multiply the number of bottles by $3, or:

3*J

Since she paid for them with a $20 bill, you need to subtract the total price of the bottles (shown above) from 20. Let's say "y" is the amount of change she receives:

y=20 - (3*J)
