3. Which dealership sells more cars per day? How many more?
The car mart sells more cars per day. They sell one more car each day.
4. Which dealership started with more cars? How many more cars did that dealership start with? Explain how you found your answer.
Car mart started with more cars. Car mart started with 65, and Winston's started with 62. We know how many cars are sold each day, so we can multiply that number by the amount of days the sale has been going on, and then add that product to the amount of cars left on that day to find the amount of cars that the sale started with.
