The atmospheric pressure P in pounds per square inch (psi) is given by the formula below, where a is the altitude above sea level (in miles). If a city has an atmospheric pressure of 13.25 psi, what is its altitude? (Recall that 1 mi = 5,280 ft. Round your answer to the nearest foot.)
P = 14.7 e**(-0.21 a)
ft

    Since you have the formula, what's the holdup? Plug in your values.

    Hint: use logs -- ln(e^x) = x

    ln P = ln 14.7 - .21a
