Lana and her friends go to a theater on the weekend to watch a new play Joan told them was live. When they arrived, Lana saw 100 cars in the front parking lot. She saw two times more vehicles at the back than there were in the front parking lot. If the total number of cars at the end of the play was 700, how many more cars packed into the parking lot during the play?

How many cars were in the back parking lot? ** The number of cars in the back parking lot was 100*2 = <<100*2=200>>200 times more than those in the front parking lot.
How many cars were in the back parking lot? ** There were 200+100 = <<200+100=300>>300 cars in the back parking lot.
How many cars were present before the play began? ** A total of 300+100 = <<300+100=400>>400 cars were present before the play began
How many cars parked in the theater during the play? ** The total number of cars that parked in the theater during the play is 700-400 = <<700-400=300>>300 cars
