Jason goes to the movies and purchases candy for $4.55. If he buys a total of 5 movie tickets and spends a total of $20.35, how much was each ticket?

Answers

3.16 per movie ticket

First you want to subtract the candy amount 4.55 from the total 20.35 that way we can get the total for the 5 tickets by themselves

20.35-4.55= 15.80

Then you want to divide the total for all five tickets by 5 which will get us the total for one ticket

15.80/5=3.16
