A car dealership has 40 cars on the lot, 30% of which are silver. if the dealership receives a new shipment of 80 cars, 40% of which are not silver, what percent of the total number of cars are silver?
silver cars before shipment = 30% of 40 = 12 silver cars after shipment = 60% of 80 = 48 Total number of silver cars out of 120 = 48+12 = 60, which is 50% E is my answer.
