im and Luke start a lawn-mowing business and buy a lawnmower for $325. They plan to charge $25 to mow one lawn. Which inequality can be used to find x, the minimum number of lawns they need to mow if they wish to earn a profit of at least $1000?

Answer 1

The inequality that can be used to find x, the minimum number of lawns they need to mow to earn a profit of at least $1000 is:

$25x - $325 ≥ $1000

Simplify the inequality:

$25x ≥ $1325

Now divide both sides by $25:

x ≥ 53

Therefore, the minimum number of lawns they need to mow to earn a profit of at least $1000 is 53.
