Answer:
Derek will buy 73 1/3 pounds of lunch meat to make 330 sandwiches
Step-by-step explanation:
People at the picnic = 300
For every 10 people 11 sandwiches will be eaten
Total sandwiches eaten by 300 people = 300/10 × 11
= 30*11
= 330 sandwiches
330 sandwiches will be eaten at the picnic
20 pounds of meat will make 90 sandwiches.
90/20 = 330/x
Cross product
90x = 330*20
90x = 6,600
Divide both sides by 90
x= 73 1/3
Derek will buy 73 1/3 pounds of lunch meat to make 330 sandwiches
73 1/3 pounds 330 sandwiches
