Chapter 6.1, Problem 124E

To determine

(a)

The cost function$C(x)$and the revenue function$R(x)$for a company, given the daily cost to the company to produce each item is $30000 with total fixed costs of $120000 and the company can sell the item for $90000 each.

To determine

(b)

The number of items the company needs to sell to break even, given the equations for cost to produce$x$items $C(x)$and the revenue from selling $x$items$R(x)$.

To determine

(c)

The profit function$P(x)$for the company and to determine what $P(x)=0$ represent, given that the equations for cost to produce$x$items $C(x)$and the revenue from selling $x$items$R(x)$were determined in the previous sections.
