Question 977226: I haved worked this question out to be x=250. What is your answer:
Suppose that the daily cost C of manufacturing bicycles is given by
C(x)= 80x + 5000. Then the average daily cost C is given by
C(x)= 80x+5000
--------
x
how many bicycles must be produced each day for the average cost to be no more than $100?

Why are you dividing the daily cost by the number of bicycles? What is your x? Best is to write the problem description and question exactly as it is given to you.

Yes you are right but you could set it out like this:
(80x+5000)/x<=100 so that we have 80x+5000<=100x, if we collect like terms, this inequality turns to: 80x-100x<=-5000 so -20x<=-5000 and x>=250.
What you left out is the inequality sign, everything else is fine.
Hope this helps!
