a) Let x be the number of pounds of meat recommended to feed 1 dozen people
1 1/2 dozen = 4 1/2 pounds
1 dozen = x
cross-multiply
1 1/2 x = 4 1/2
3/2 x = 9/2
Multiply both-side of the equation by 2/3
x = 9/2(2/3)
x = 3
Therefore, 3 pounds is rcommended to feed 1 dozen of people.
b) To find the number of pounds recommended to feed 4 people;
1 dozen = 12
12 people = 3pounds
4 people = x
cross-multiply
12x = 12
Divide both-side of the equation by 12
x= 1
Hence, 1 pound is recommended to feed 4 people
