Answer: Option 'A' is correct.

Step-by-step explanation:

Cost of 9 ounces of apples = $1.89

Cost of 1 ounce of apple is given by


(1.89)/(9)=\$0.21

Now, if he bought 1 pound of apple,

Cost of 1 pound of apple = $2.49

Cost of 16 ounces = $2.49

(∵ 1 pound = 16 ounces)

Cost of 1 ounce of apple is given by


(2.49)/(16)=\$0.156

So, Second option is the least expensive if he bought 1 pound of apple for $2.49

Then, he will save which is given by


0.21-0.156=0.054* 16=$0.87\ per pound

Hence, option 'A' is correct.
