Answer:
The marginal cost at the given production level is $49.9.
Step-by-step explanation:
The marginal cost function is expressed as the first derivative of the total cost function with respect to quantity (x).
We have that the cost function is given by

So, we need the derivative and then we’ll need to compute the value x = 100 of the derivative.

When x = 100, the marginal cost is

If the Hans leave for 3 days, and Tish wants to feed the dogs 3 cans each day, we can solve this problem using simple multiplication.
3 days * 3 cans / 1 day = 9 cans
