Mei subscribed to a magazine at a rate of $24 for 12 issues. When she placed her order, Mei used a coupon that added 3 free bonus issues to her subscription. How did the coupon impact the cost per issue of Mei’s subscription?
The coupon lowered the cost per issue by $0.40.
The coupon lowered the cost per issue by $1.38.
The coupon raised the cost per issue by $0.13.
The coupon raised the cost per issue by $0.67.
To find the cost per issue of Mei's subscription, we need to divide the total cost by the number of issues.
Before the coupon, Mei is paying $24 for 12 issues, so the cost per issue is $24 / 12 = $2.
After using the coupon, Mei gets an additional 3 free bonus issues. This means she now has a total of 12 regular issues + 3 bonus issues = 15 total issues.
However, she still paid $24 for her subscription, so the cost per issue is now $24 / 15 = $1.60.
Therefore, the coupon lowered the cost per issue by $2 - $1.60 = $0.40.
So the correct answer is: The coupon lowered the cost per issue by $0.40.
