A certain group of car dealerships agreed to donate x dollars to a Red Cross chapter for each car sold during a 30-day period. What was the total amount that was expected to be donated?
1) A total of 500 cars were expected to be sold 2) 60 more cars were sold than expected, so that the total amount actually donated was $28,000
