Matched Problem 4 Repeat Example 4 with production increasing from 6,000 to 6,010. EXAMPLE 4 Cost–Revenue A company manufactures and sells x microprocessors per week. If the weekly cost and revenue equations are C ( x ) = 5 , 000 + 2 x R ( x ) = 10 x − x 2 1 , 000 0 ≤ x ≤ 8 , 000 then use differentials to approximate the changes in revenue and profit if production is increased from 2,000 to 2,010 units per week.

Solution Summary: The author calculates the rate of changes in revenue and profit if production from 6,000 to 6,010 units per week by using the differentials.
Assuming that the rate of change of the price P of a certain commodity is proportional to the difference between demand D and supply S at any time t, the differential equations describing the price fluctuations with respect to time can be expressed as: dP/dt = k(D - s) where k is the proportionality constant whose value depends on the specific commodity. Solve the above differential equation by expressing supply and demand as simply linear functions of price in the form S = aP - b and D = e - fP
