Question 7. A manufacturer of jet engines estimates that the rate at which maintainance costs are incurred on its engines is a function of hours of operation of the engine. For one engine used on commercial aircraft, the function is r(t) = 40 + 0.03t 2 where t equals the number of hours of operation and r(t) equals the rate at which repair costs are incurred in dollars per hour of operation. What are the total maintainance costs expected to equal during the first 100 hours of operation?

Question 7. A manufacturer of jet engines estimates that the rate at which maintainance costs are
incurred on its engines is a function of hours of operation of the engine. For one engine
used on commercial aircraft, the function is r(t) = 40 + 0.03t
2 where t equals the number
of hours of operation and r(t) equals the rate at which repair costs are incurred in dollars
per hour of operation. What are the total maintainance costs expected to equal during
the first 100 hours of operation?
