Question

POSSIBLE POINTS 7.69 David knows a 12-pound ham will feed 9 people. If 72 people are coming to David's home for a party, at this rate how many pounds of ham will he need?

Answer 1

Given:

a 12-pound ham will feed 9 people.

so, the unit rate will be:

`(12)/(9)=(4)/(3)`

Which mean David need 4/3 pound of ham for each person

So, If 72 people are coming to David's home for a party

The pounds of ham =

`(4)/(3)\cdot72=96`

So, he will need 96 pounds of ham.
