A construction worker bought several bottles of juice for $3 at the convenience store. She paid for them with a $20 bill. If j represents the number of bottles of juice, write an expression for the change she should receive
20 - 3j I guess it would be this. Since 20 is the total minus 3(price for the juice) multiplied by the number of bottles of juice. we should get a total of cost charged for, subtract from 20 and get the change amount.
