Solve the problem.
If the average cost per unit C(x) to produce x units of plywood is given by:

C(x) = 900 / x + 30
What do 600 units cost? Round your answer to the nearest cent.

b. $899.95
c. $180.00
d. $18,000.00

You can put this solution on YOUR website!
I think you have an incorrect equation because non of your optional answers mahch the equation.
--------------------------------------
C(x) = 900 / (x + 30)
c(x)=900/630
c(x)=1.428 is the cost per unit.
c(600)=900/600+30
c(600)=1.5+30
c(600)=$31.50 is the cost per unit of plywood.
