Kara bought 5 pounds of brand x roast beef for $43. cameron bought 3 pounds of brand y roast beef for $27. which brand of roast beef is the better buy?

Hey there Jefferymcdougl1,

Brand X:
5 pounds = $43
1 pound = $43 / 5
              = $8.60

Brand Y:
3 pounds = $27
1 pound = $27 / 3
              = $9
Thus, Brand X is a better buy as Brand Y costs $0.40 more than Brand x

Hope this helps :D

Compare the two by dividing.

X:
43/5 = $8.6/lb

Y:
27/3 = $9/lb

So, Y has a greater price per pound than X. This means that Brand X which Kara bought was the better buy by $0.4/lb.

The correct answer is c
