Question
As machines get older, the cost of maintaining them tends to increase. Suppose for a particular
machine, the rate at which the maintenance cost is increasing is approximated by the function
C' (t) = (5t+30)√0.5t² + 6t, for 0 ≤ t≤ 15,
where C' is the maintenance cost in dollars and t is the number of years since the purchase. The
company will sell or scrap the machine in 15 years and buy a new one if the cost to maintain it in its
last year of service is projected to exceed $1,500. Round monetary answers to the nearest cent.
