Answer:
f(g) = 3g + 2
Step-by-step explanation:
slpoe-intercept formula: y=mx+b
y ( or f(g) ) = money spent bowling
x (or g) = games played
b = cost to rent shoes
Since you only have to pay for shoes once, that is your starting point (or b).
You have to pay every game you play, so the amount spent playing the games themselves is $3 * the amount of games played (or g).
Therefore,
f(g) = 3g + 2
