SOLUTION: The equation P(a) = 14.7e^(-0.2a), where a is the altitude above sea level in miles, yields the atmospheric pressure in pounds per square inch. If the atmospheric pressure at Cheye

Question 960539: The equation P(a) = 14.7e^(-0.2a), where a is the altitude above sea level in miles, yields the atmospheric pressure in pounds per square inch. If the atmospheric pressure at Cheyenne, WY is approximately 11.73 pounds per square inch find that city's altitude above sea level.
Not sure how to set this one up.

Replace the variable a in your function with 11.73 and solve for P(11.73). In other words, replace every a in the function with 11.73 and do the math.
