Question 111987
We've already been given a general equation that represents the cost of production,
0.07W + 13.3
This menas that 13.3 is a base rate, no matter what quantity you use, this cost will always be applicable.  And the 0.07W gives us the exact cost of production for each part manufactured.
With this, realizing that W is the quantity, we can plug in the quantities and find the total cost of production.
Were W = 375:
0.07(375) +13.3 = 39.55
So when the quantity is 375, the cost of production is 39.55
Where W = 1:
0.07(1) + 13.3 = 13.37
So when the quantity is 1, the total cost of production is 13.37
