Tony needs to buy some pencils. Brand A has a pack of 28 pencils for 5.29 dollars. Brand B has a pack of 48 pencils for 8.47 dollars. Find the unit price for each brand then state which brand is the best buy based on the unit price round your answer to the nearest 10th

Brand A is the best buy.

Step-by-step explanation:

Brand A has a pack of 28 pencils for 5.29 dollars. This means that the unit cost of one pencil in Brand A would be

5.29/28 = 0.2$ per pencil rounded up to the nearest tenth.

Brand B has a pack of 48 pencils for 8.47 dollars. This means that the unit cost of one pencil in Brand B would be

8.47/48 = $0.8 per pencil rounded up to the nearest tenth.

Since $0.2 is lesser than $0.8, it means that Brand A is the best buy.
