A bowling 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
Answer: 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
