Hmm, well, I dunno either, but the sum is 132, maybe that will help a little! I'm sorry if it doesn't.
C. $4.50 for 9 cans would be the correct answer
2n - 3 ≥ 5
Add 3 to both sides.
2n ≥ 8
Divide both sides by 2
n ≥ 4
That's the first part of our inequality. Let's get the second part.
2n - 3 ≤ 7
Add 3 to both sides.
2n ≤ 10
Divide both sides by 2
n ≤ 5
Our compound inequality is: 4 ≤ n ≤ 5
15x + 18y ≥ 120 would be the inequality
