Use differentials to approximate the change in cost corresponding to an increase in sales (or production) of one unit. Then compare this with the actual change in cost. (Round your answers to two decimal places.) Function x-Value C = 0.075x2 + 6x + 7 X = 10 dollars dc = AC = dollars Need Help? Raadi Wis This to a Tutor 2. (-/2 Points] DETAILS LARAPCALC10 3.8.016.

The demand function for a product is p= 108 - 0.2x where p is the price per unit(in dollars) and x is the number of units. a. Use differentials to approximate the change in revenue as sales increase from 20 units to 21 units. Compare this the actual change in revenue. b. Repeat step (a) when sales increase from 40 units to 41 units.
A commodity has a demand function modeled by p = 280 − 0.4x, and a total cost function modeled by C = 80x + 120, where x is the number of units. (a) What price yields a maximum profit? (b) Find the average cost per unit when x = 50 and x = 650. (c) Determine when the demand is elastic, inelastic, and of unit elasticity. (d) Use differentials to approximate the change in revenue as sales increase from 210...
