Question

The equation a = 640s gives the relationship between s square miles and a acres. Pam owns 7.5 square miles of farmland. How many acres does she own? Question 2 options: 4,800 acres 1.17 acres 480 acres 11.72 acres

Answer 1

4,800 acres

Explanation:

The equation is

`a=640s`

where
`s` is square miles and
`a` is acres.

If Pam owns
`7.5` square miles of farmland, then
`s=7.5`.

We need to substitute this value into the given equation to determine the acres she has.

This implies that,

`a=640* 7.5`

We multiply to get,

`\Rightarrow a=4800`

Therefore Pam has 4,800 acres.

The correct answer is A
