Question

The equation a=640s gives the relationship between s square miles and acres. Pam owns 7.5 square miles of farmland. How many acres does she own

Answer 1

640 acres / 1 mi^2

7.5 mi^2 (640 acres / 1 mi^2)

= 4,800 acres

Answer 2

4800 acres.

Explanation:

We have been given an equation
`a=640s`, which gives the relationship between s square miles and acres.

To find the number of acres Pam owns we will substitute
`s=7.5` in our given equation.

`a=640* 7.5`

`a=4800`

Therefore, Pam owns 4800 acres.
