To find out how much more glow-bowling costs per game compared to the early-bird special, we first need to determine the cost per game for each option.
Glow-bowling on Friday night:
- Total cost: $22.50
- Number of games: 5
Cost per game for glow-bowling: \[ \text{Cost per game} = \frac{\text{Total cost}}{\text{Number of games}} = \frac{22.50}{5} = 4.50 \]
Early-bird special on Saturday morning:
- Total cost: $30
- Number of games: 8
Cost per game for the early-bird special: \[ \text{Cost per game} = \frac{\text{Total cost}}{\text{Number of games}} = \frac{30}{8} = 3.75 \]
Comparing the costs per game:
- Glow-bowling: $4.50 per game
- Early-bird special: $3.75 per game
To find how much more glow-bowling costs per game: \[ \text{Difference} = \text{Cost per game (glow-bowling)} - \text{Cost per game (early-bird)} = 4.50 - 3.75 = 0.75 \]
Thus, glow-bowling costs $0.75 more per game than the early-bird special.
