What Is the Answer To number 1 ?
DochEvi [55]

Answer: 4 apples for $3.64


Step-by-step explanation:

The best buy is going to be the one that costs the least. To figure this out, you divide the number of apples by the price. (do not round)

4/3.64=1.09

9/8.01=1.23

14/12.43=1.12

24/21.12=1.13

As you can see, the 4 apples for $3.64 is the better choice since the number is the least.
