Respuesta :

Answer: Option 'A' is correct.

Explanation:

Cost of  9 ounces of apples = $1.89

Cost of 1 ounce of apple is given by

[tex]\frac{1.89}{9}=\$0.21[/tex]

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

[tex]\frac{2.49}{16}=\$0.156[/tex]

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

[tex]0.21-0.156=0.054\times 16=$0.87\ per pound[/tex]

Hence, option 'A' is correct.
