Question 1

The marginal cost of producing the xth box of light bulbs is 9 20000 , and the fixed cost is $20,000. Find the cost function C(x). HINT [See Example 5.] C(x) = 111e marginal cost function for the manufacture of wireless headphones is given by X 100 ' CO!) = 4n where x is the number of headphones manufactured. Use a (left) Riemann sum with n : 5 to estimate the oost of producing the rst 5 headphones. (Round your answer to the nearest cent.) $|:|
