Answer 1

Total amount spent on 4.6 pounds of ground beef = $16.33

We have to determine the amount spend on 3 pounds of ground beef.

We will use unitary method to solve this problem.

So, amount spent on 1 pound of ground beef =
`$16.33 / 4.6`

= $3.55

So, amount earned on 3 pounds of ground beef =
`3 * $3.55`

= $10.65

Therefore, Lena will spend $10.65 on 3 pounds of ground beef.

So, Option C is the correct answer.
