<PRE><B>Question 100820</B>
The cost in dollars of manufacturing w wing nuts is given by the expression 0.07w + 13.3. Find the cost when 375 wing nuts are made. What is the average cost to manufacture one wing nut?
----------------------------------
The price of each wing nut is (0.07w+13.3)/w.
So the price of 375 nuts is 375[(0.07w+13.3)/w]
= (26.25w + 4987.5)/w

= (26.25 + (4987.5/w))
