Answer:
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
