SOLUTION: Atmospheric pressure P (in kilopascals, kPa) at altitude h (in kilometers, km) is governed by the formula ln(P/P0 = -h/k where k = 7 and P0 = 100 kPa are constants. Solve

Question 1040454: Atmospheric pressure P (in kilopascals, kPa) at altitude h (in kilometers, km) is governed by the formula
ln(P/P0 = -h/k
where k = 7 and P0 = 100 kPa are constants.
Solve the equation for P.
I got 100e^{-k/7} WRONG!!!

ln(P/P0 = -h/k
where k = 7 and P0 = 100 kPa are constants.
Solve the equation for P.
-----------
ln(P/P0) = -h/k
ln(P/100) = -h/7
P/100 = e^(-h/7)
P = 100*e^(-h/7)
