    What equation would you use to find the height of the air pressure when it is 75% of the air pressure at sea level???

    first solve that equation for h. so that on one side you would have h=the rest of the formula. and then solve it.

    so then set .75 equal to the equation?

    If \(\Large P_0\) is the pressure at sea level, then 75% of this pressure is \(\Large 0.75P_0\) so we replace P(h) with \(\Large 0.75P_0\) |dw:1433451680756:dw|

    You'll find that the \(\Large P_0\) terms cancel out (when you divide both sides by \(\Large P_0\)) |dw:1433451757312:dw|

    so you'll be left with \[\Large 0.75 = e^{-0.0012h}\] solve for h to get the height needed
