Question

The dollar cost of producing 𝑥x bagels is 𝐶(𝑥)=300+0.25𝑥−0.7(x/100)^3

Determine the cost of producing 3500 bagels:

𝐶(3500) =  dollar …

Estimate the cost of the 3501 st bagel:

The cost of the 3501 st bagel is dollar=

 Find the actual cost of the 3501 st bagel:

The actual cost of the 3501 st bagel is dollar=

Answer 1

Actual cost of 3501st bagel is

C(3501) - C(3500)

Just do a lot of arithemetic.
