Question: Tyson decided to make muffaletta sandwiches for the big game.  Each sandwich required 1 pound each of meat and cheese and would serve 4 people.  There would be 20 people in total watching the game.  The meat cost $7.00 per pound and the cheese cost $3.00 per pound.  How much money would he spend on the meat and cheese to make enough sandwiches to serve 20 people?
Solve it. 
Answer: 
Each sandwich serves 4 people and he had 20 people in total to make food for so 20/4 = 5 sandwiches
1 pound of meat cost $7.00 per sandwich and he had to make 5 so 7*5 = $35.00 for meat
1 pound of cheese cost $3.00 per sandwich and he had to make 5 so 3*5 = $15.00 for cheese
When you add the meat and cheese together, he would spend 35+15 = $50.00
