Abowling alley has a fixed base cost and charges a variable per game rate. it costs $20.50 for five games and $28.50 for nine games, what is the variable cost

2
 Work: Substract 28.5 minus 20.5 = 8 Then substract 9 - 5 = 4
Then put them as a fraction like 8/4
Put it as a unit rate or divide 8 by 4 and that equals 2. Hope it helps!
Oh and there's also a website in Google with all the answers with the work! :D
