Question
A airplane crosses the Atlantic Ocean (3000 miles) with an airspeed of 600 miles per hour. The cost C (in dollars) per passenger is given by...
C(x)= 150 + x/20 + 36,000/x
Where x is the ground speed (airspeed plus or minus wind).
a. What is the cost per passenger for quiescent (no wind) conditions?
b. What is the cost per passenger with a head wind of 50 miles per hour?
c. What is the cost per passenger with a tail wind of 100 miles per hour?
d. What is the cost per passenger with a head wind of 100 miles per hour?
C(x)= 150 + x/20 + 36,000/x

ground speed (x) = 600 +- wind speed
then use the formula, Tail wind add wind speed, headwind, subtract.
