A construction worker bought several bottles of juice for $3 at the convenience store. she paid them with a $20 bill. If J represents the number of bottles of juice, write an expression for the change she should receive.​

Respuesta :

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
