Detailed Solution to Practice #11

The package of boneless chicken costs $3.15 for 1.5 pounds. Ground beef costs $5.48 for 2 pounds. Which of these two would be a better buy, in terms of pounds of food per dollar.

Below is the detailed solution to this practice.

The first thing we need to do is set up a table for our information.

	Cost (in $)	Size (in lbs.)	Ratio
Chicken	3.15	1.5
Beef	5.48	2.0

We need to determine the ratio that goes in the last column. We will use the ratio of Cost/Size, or dollars per pound.

Ratio Cost/Size for Chicken:
Ratio Cost/Size of Ground Beef:

We can now fill in the table:

	Cost (in $)	Size (in lbs.)	Ratio
Chicken	3.15	1.5	$2.10/ lb
Beef	5.48	2.0	$2.74/ lb

When we compare these, we can see that the chicken is a better buy.

If you feel you need further review before trying the additional practice, reread this unit.
