A factory's cost function is $C(m, t) = 200mt + 1000m + 800t + 5000$, where $m$ is
the number of machines run during the week, $t$ is the number of hours the factory
operates that week, and $C$ is the total weekly cost in dollars.
a) Calculate $C(10,50)$. Please include the proper units for this value.
b) Given $C(8, t) = 109,000$, solve for $t$. Please include the proper units for this
value.
