A subscription for 15 magazines cost $45. the same company is offereing 25 magazines for $70. which is a better deal? why?

Answer 1

25 magazines for $70. (For why, read explanation)

Explanation:

We can find the unit price of each of these deals by dividing the cost and the quantity.

`(45)/(15)` = 3, so the first deal is $3 per magazine.

`(70)/(25)` = 2.8, so the second deal is $2.80 per magazine.

Therefore, 25 magazines for $70 is a better deal.

Hope this helped!
