The admission fee to a video game arcade is $1.25 for each person, and it costs $0.50 for each game played. Which expression represents the amount Larry and Donna will spend for g games played?
Larry and Donna have a total of $10.00 to spend. What is the greatest number of games they will be able to play?

number of games ---- g

cost = 1.25 + .5g

assuming they both pay 1.25 to get in ...
2.50 + .5g = 10
.5g = 7.50
g = 15

They can play at most 15 games
