Answer:
500
Explanation:
The total cost of producing a type of boat is given by C(x) = 13000 - 10x + 0.01x²........ (1), where, x is the number of boats produced.
Now for cost to be minimum

So, differentiating equation (1), we get - 10 + 0.02x = 0
⇒ x =

Therefore, 500 total boats should be produced to incur minimum cost. (Answer)
