Question

Target is advertising a Back to School sale on pens. A pack of 30 sells for $8.90, whereas a 15-pack of me same brand costs $4.39. Which is the better buy? How do you know? ​

Answer 1

Answer: Well you don't really need to do math. You have to think half of 30 is 15. So then you would multiply 4.39 times 2 and you get 8.78. So the 15 pack is a better deal.
