Answer:
One pound of ground beef costs $2.75.
Explanation:
To solve this you want to divide both numbers by 3.4 this is because you want to find out much the ground beef costs per 1 pound and 3.4 / 3.4 = 1. Additionally, what you do to one side you must do to the other!
3.4 / 3.4 = 1
9.35 / 3.4 = 2.75
One pound of ground beef costs $2.75.
