Hello,
The answer would B. This is a tricky question in the way it's worded but we're given in 4.7 4 has a value of number 4 (in the ones place) and in 5.4, 4 has a value of 4 in the tenths place. The easiest way to think about this is, if we multiply 5.4 by 10 we get 54. And in 54 the number 4 has a value of 4, so 10 or B is the answer. Hope this helps!

Step-by-step explanation:
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.
