SOLUTION: The average atmospheric pressure P is pounds per square inch is P = 14.7e-0.21x where x is the altitude in miles above sea level. Find the average atmospheric pressure for an alti

Question 40616: The average atmospheric pressure P is pounds per square inch is P = 14.7e-0.21x where x is the altitude in miles above sea level. Find the average atmospheric pressure for an altitude of 3 miles. Round the answer to the nearest tenth.
Thanks for anyones help
