(13) A charter bus company has determined that the cost of providing x people a tour is

C(x) = 180.00 + 2.50 x.

A full tour is 60 people. The cost of a ticket is $15.00 plus $0.25 for each unsold ticket. Determine (a) the revenue function, (b) the profit function, (c) the company’s maximum profit, and (d) the number of ticket sales that yields the maximum profit.

a) The revenue function gives the revenue when $x$ tickets are sold:

$R(x)=[15+(60-x)\times 0.25]x$

That is the price of a single ticket is $\$[15 +(60-x) \times 0.25]$ when $x$ tickets are sold.

b) The profit function is:

$<br /> P(x)=R(x)-C(x)<br />$
