Question

The cost function for a company is C(x) = 90x + 1,800, where x is the number of bicycles produced at a cost of $90 each. How many bicycles can be produced for $3,780?

Answer 1

22

Explanation:

• If the total cost of production can be explained with the function
  `C(X)=1.800+90X`, then when this total cost equals $3.780, we know that
  `3.780=1.800+90X`.
• Subtracting 1.800 both sides of the equation yields
  `1.980=90X`.
• Finally, dividing both sides by 90 gives us the value of X=22.
• Then, with $3780 we can produce 22 bicycles.
