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

Answer:

4800 acres.

Step-by-step 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.

$a=640\times 7.5$

$a=4800$

Therefore, Pam owns 4800 acres.
