Answer
Ans: 5.6 grams of ground beef will cost 15.63 dollars.
Work Step by Step
Let's assume the costing is x dollars.
Now, we will write the proportion for the given details
$\frac{3.5 pounds}{9.77 dollars} = \frac{5.6 pounds}{x dollars}$
so. $ 3.5\times x= 5.6\times 9.77$ (Same units cancelled)
Now divide both sides by 3.5.
$\frac{3.5 x}{3.5} = \frac{54.71}{3.5}$
$ x = 15.63 $
5.6 grams of ground beef will cost 15.63 dollars.
