The expression for the change received = $20 - 3 J

Step-by-step explanation:

The cost of 1 juice bottle = $3

Let us assume the number of juice bottles bought = J

The amount of bill paid = $20

Now, the cost of J juice bottles = J x (Coat of 1 juice bottle)

= J x ($3) = 3J

Now, the Change Returned = $20 bill - The cost of J juice bottles

= $20 - 3 J

or, Change Returned = $20 - 3 J

Hence, the expression for the change received = $20 - 3 J
