Question

The table show the relationship of how many pounds of cherries are needed to make a certain number of pies: pies 6 12 18 cherries 4 8 12

Answer 1

M=dc/dp=4/6=4/6=2/3

c(p)=2p/3 +b  using (6,4)

4=2(6)/3+b

4=4+b, b=0 so

c(p)=2p/3  

(the number of cherries needed as a function of the number of pies)
