Answer:
2 lbs. for $4.50
Explanation:
Do a ratio
2 : 4.50
You want to see how much it cost per pound, so divide them by 2
2 ÷ 2 : 4.50 ÷ 2
1 : 2.25
So per pound, the hamburger will cost $ 2.25

3 : 6.90
You want to see how much it cost per pound, so all you need to do is divide them by 3
3 ÷ 3 : 6.90 ÷ 3
1 : 2.3
So for the first one, it cost 2.25 per pound, and for the second one, it cost 2.3 per pound....the one that is better will be 2.25 because it cost 5 cents less than the second one
Hope this helped!
