Hey guys, here's the problem and what I've got so far.
A contractor purchases a piece of equipment for $36500 that costs an average of $9.25 per hour for fuel and maintenance. The equipment operator is paid $13.50 per hour, and customers are charged $30 per hour.
(a) Write an equation for the cost C of operating this equipment for t hours
(b) Write an equation for the revenue R derived from t hours of use
(c) Find the break-even point for this equipment by finding the time at which R = C
What I've got:
(a)
[tex] C = 22.75(t)+36500[/tex]
(b)
[tex]R=30(t)+36500[/tex]
(c - worked out)
[tex]0 = -7.25(t) + 36500[/tex]
[tex]5034.48 = t[/tex]
does this look right?
