MODELING REAL LIFE 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 surface area $A$ (in square inches) of the soles of your footwear. Write an equation that gives $P$ as a function of $A$ when a hiker wears the snowshoes shown and the pressure is 0.43 pound per square inch. Then find the pressure when the hiker wears the boots shown.
