A force of 22 pounds presses on a membrane. The average pressure on the membrane is 2.75 pounds per square inch (psi). What is the area of the membrane in square inches? The equation for calculating pressure is where P is pressure, F is force, and A is area.

MODELING WITH MATHEMATICS When you stand on snow, the average pressure P (in pounds per square inch) that you exert on the snow varies inversely with the total area A (in square inches) of the soles of your footwear. Suppose the pressure is 0.43 pound per square inch when you wear the snowshoes shown. Write an equation that gives P as a function of A. Then find the pressure when you wear the boots shown. | Numerade
