Question

.

Answer 1

I received 1/2 points for my response of "Seeing as the cost per share is 20 we now have the equation of 20=500/n, solving this we can get n=500/20 which converts into 50/2 which finally converts into 25 which is your answer of how many new contributors are needed."

Answer 2

you received half the points because you only solved for the second question

Answer 3

the first question ask you to find a function models the cost per share, C, with respect to the number of new contributors, n.

and that would be

C=500/n

Answer 4

How did you come up with that answer, if you don't mind me asking
