Jean goes to a movie theater where a ticket costs $7 and any snack
 item-candy,popcorn,or drink-sells for $1.50 each. 
Frank goes to a theater where the ticket costs $4 and candy, popcorn,
 or drinks sell for $2.50 each. 
How many snack items would jean and Frank need to buy, so that they
 each pay the same amount at the theater?
:
Let n = number of snack items bought for equal amts
:
Franks$ = Jeans%
 2.50n + 4 = 1.50n + 7
2.5n - 1.5n = 7 - 4
n = 3 snack items

Check solution in original equation
