Question

Friday night is glow bowling with 5 glow bowling games for $22.50 but the early bird special on Saturday morning offers 8 games for $30. How much more does glow bowling cost per game?

Answer 1

Glow bowling costs $0.75 more per game.

Explanation:

`friday \: night \\ (5 \: games)/(22.50 \: dollars) = (1 \: game)/(x) \\ \\ (22.50)/(5) = (5x)/(5) \\ \\ x = 4.5`

`saturday \: morning \\ (8 \: games)/(30 \: dollars) = (1 \: game)/(x) \\ \\ (30)/(8) = (8x)/(8) \\ \\ 3.75 = x`

Then we just subtract:
`4.5 - 3.75 = 0.75`
