    1. The following function represents the cots in hundreds of dollars for producing pens, where x represents 1000's of units
    c(x)=.4x^2-16x+200 , 25 ≤ x ≤ 40

    a) Estimate the cost for making the 36th 1000-unit run using the marginal cost function derivative.

    b) Find the actual cost for making the 36th 1000-unit run.
