How many meatballs are required for a party of 10 adults and 5 children?

Question

Frank has devised a formula for his catering business that calculates the number of meatballs he needs to prepare. The formula is m=4a+2c,where c= number of children ;m=number of meatballs;a=number of adults. How many meatballs are required for a party of 10 adults and 5 children?

Answer 1

You can solve this by substituting the a and c values that the problem gives you. Plug in 10 for a and 5 for c. Then just evaluate:

 

m = (4×10) + (2×5)
