Boyle's law states that if the temperature of a gas remains constant, then PV = c , where P = pressure, V = volume, and c is a constant. Given a quantity of gas at constant temperature, if V is decreasing at a rate of 9in^3/sec, at what rate is P increasing when P = 80lb/in ^ 2 and V = 40in^3 ? (Do not round your answer.) Note*** Answer will be ( lb/in^2 per sec) Thank you
