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
Blizzard [7]
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

Hope this helps
