Question 772524: The atmospheric pressure P in pounds per square inch (psi) is given by
P = 14.7 e−0.21 awhere a is the altitude above sea level (in miles). If a city has an atmospheric pressure of 12.25 psi, what is its altitude? (Recall that 1 mi = 5,280 ft. Round your answer to the nearest foot.)

, so for 
,
Take the natural log of both sides:
\ =\ \ln\left(\frac{5}{6}\right))
Then use \ =\ \varphi\log_b(x))
and \ =\ 1)
\ =\ \ln\left(\frac{5}{6}\right))
)
}{-0.21})
Do the arithmetic and round off.
