Problema Solution
Joy wants to make burgers for 12 family members. She bought a 4 pound package of ground sirloin that serves 8 people. How much more meat should Joy purchase?
Answer provided by our tutors
let x = lbs of meat needed for 12 family members
since the weight of the meat is directly proportional with the number family members we have:
4 : 8 = x : 12
by solving we find:
x = 6 lbs
