Store A: 25/45 = $.56 / min
Store B: 30/60 = $.50 / min
Store C: 45/90 = $.50 / min , same as B
Store C: 80/180 = $.44/ min
so C is the best deal
To find the store with the best deal based on the lowest cost per minute, we need to calculate the cost per minute for each store.
Store A: $25 for a 45-minute lesson
Cost per minute: $25 / 45 minutes = $0.56 per minute
Store B: $30 for a 1-hour lesson
Cost per minute: $30 / 60 minutes = $0.50 per minute
Store C: $45 for a 1.5-hour lesson
Cost per minute: $45 / 90 minutes = $0.50 per minute
Store D: $80 for three 1-hour lessons
Total cost for 3 hours: $80
Cost per minute: $80 / (3 hours * 60 minutes per hour) = $0.44 per minute
Based on the lowest cost per minute, Store D has the best deal with a cost of $0.44 per minute. Therefore, the correct answer is:
D - Store D
To find the store with the best deal based on the lowest cost per minute, we need to calculate the cost per minute for each store.
Store A: $25 for a 45-minute lesson
Cost per minute = $25 / 45 minutes = $0.56 per minute
Store B: $30 for a 1-hour lesson
Cost per minute = $30 / 60 minutes = $0.50 per minute
Store C: $45 for a 1.5-hour lesson
Cost per minute = $45 / (1.5 * 60 minutes) = $0.50 per minute
Store D: $80 for three 1-hour lessons
Total minutes = 3 * 60 minutes = 180 minutes
Cost per minute = $80 / 180 minutes = $0.44 per minute
Based on the lowest cost per minute, Store D has the best deal with a cost of $0.44 per minute. Therefore, the correct answer is:
D Store D
