Joe knows a 5-pound turkey breast will feed 8 people. if 20 people are coming to joe's home for dinner, at this rate how many pounds of turkey breast will he need?

To find out how many pounds of turkey breast Joe will need for 20 people, he can set up a proportion and solve for x, the amount of turkey he needs.

pounds of turkey          5          x
# of people                  8     =  20

Use cross products to solve for x.

8x = 5 x 20
8x = 100
8      8
x = 12.5 pounds

Joe will need 12.5 pounds of turkey.

I’m not gonna do that
