Final answer:
To find the difference in cost of bowling 3 games at two different alleys, we compare the total cost at each. The first alley costs $10 for 3 games, while the second costs $10.80. The difference is $0.80, an option not provided in the question.
Step-by-step explanation:
The question is asking for the difference in cost between bowling 3 games at two different bowling alleys. To calculate this, we must consider both the shoe rental fee and the cost per game at each alley.
For the first bowling alley, the cost of shoe rental is $4 and the cost per game is $2. So, for 3 games, the total cost would be:
$4 (shoes) + $2/game × 3 games = $4 + $6 = $10.
For the second bowling alley, the shoe rental is $6 and the cost per game is $1.60. The total cost for 3 games would be:
$6 (shoes) + $1.60/game × 3 games = $6 + $4.80 = $10.80.
The difference in cost between the two alleys for 3 games is:
$10.80 - $10.00 = $0.80.
This result is not among the provided options, leading to the conclusion that there might be an error in the question or in the options given.
