Answer: 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.
