Question 1097202: A jet crosses the ocean with an airspeed of 430 miles per hour. The cost C (in dollars) per passenger is given by C(x)=130+x/12+35,500/x
A) What is the cost per passenger if there isn't any wind? Round your answer to two decimals.
B) What is the cost per passenger if there is a tail wind of 60 miles per hour? Round your answer to two decimals.
C) What is the cost per passenger if there is a head wind of 50 miles per hour? Round your answer to two decimals.
I've tried putting zero for x in A, i've tried putting 60 for x in the 35,000/x fraction, and tried the 50 miles per hour in the x/12. I can't seem to completely understand this problem or how to set it up properly. I've looked in my book (Not the best book) and online. Thank you in advance!!

x= airspeed (assumed) which is for A 430 mph, B 490 mph and C 380 mph. Use those for x in each of the problems.
C(430)=130+(430/12)+35,500/430=$248.39
C(490)=130+490/12+35500/490=$243.28
C(380)=130+(380/12)+(35500/380)=$255.09
