A company manufactures mountain bikes. The research department produced the marginal cost function C′​(x)=500− x 3​, 0≤x≤900​, where C′​(x) is in dollars and x is the number of bikes produced per month. Compute the increase in cost going from a production level of 600 bikes per month to 720 bikes per month. Set up a definite integral and evaluate it.
