Help please! Boyle's law for confined gases states that if the temperature is constant, pv=c where p is pressure,V is volume, and c is a constant. At a certain instant the volume is 75 cubic inches, the pressure is 3 psi, and the pressure is decreasing at the rate of 2 psi every minute. What is the rate of change of the volume at that instant?

    ok so this is as far as I've gotten with this pc=c so 75*3=225 and if it decreasing at 2 psi a minute then after one minute c=75 and after 2 c= -75 so i would say its decreasing at a rate 150 psi's a minute
