Pilot and Copilot Problem. A pilot on a commercial airline makes $100 per
hour, and a copilot makes $70 per hour. On a particular flight the copilot arrived
early to check out the airplane. Let x be the number of hours the copilot has
been on the job.
a.
Write the definition of x. Then write an expression for the number of
dollars the copilot earned in x hours.
b. The pilot starts to work 3 hours after the copilot. Write an expression in
terms of x for the number of hours the pilot has been on the job, and
another expression for the number of dollars the pilot has earned.
C. Write an equation stating that each has earned the same number of dollars.
How many hours has the copilot been on the job when this occurs?
d. How much money, total, will they earn if they both finish work after the
copilot has been on the job for 12 hours?
