A.) $0.87
B.) $0.10
C.) $0.60
D.) $0.21

Answer 1

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.
