Write a system of equations to describe the situation below, solve using any method, and fill in the blanks.

Mr. Robinson, the owner of two car dealerships in Clarksville, is holding a contest to see which one can sell the most cars. Clarksville Cars has already sold 15 cars, and Robinson's Autos has sold 13 cars. Going forward, the salespeople at Clarksville Cars think they can sell 8 cars per day, whereas the salespeople at Robinson's Autos are aiming for sales of 10 cars per day. If the salespeople's predictions are accurate, it won't be long before the two dealerships are tied. How many cars will each lot have sold? How long will that take?


The dealerships will each have sold
cars in
days.
