A manufacturer develops a formula to determine the demand for its product depending on the price in dollars. The formula is D=2,000+100p-6p^2 where P is the price per unit and D is the number of units in demand. What is the max price and max demand?

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.
