Question

It's costs $3 to bowl a game and $2 for shoe rental. How do you write an expression for cost of g games?

Answer 1

If shoes are for all games in row, `P=2+3g`
If not, `P=5g`,with g the number of games

Explanation:

The price depends:if shoes are included for the whole games, you just have to pay them once and then you have to pay `g games`, so `P(g) = 2+3g`
Else, you have to pay `g shoes and g bowl party`, so `P(g)=2g+3g <=> P(g) =5g`
