A concert promoter charges $65 per ticket for a concert. The promoters cost will be $5500 plus $4 per ticket.

If r=revenue and n= number of tickets sold, then r(n) shoes how revenue (amount of money received from tickets sales) depends on the number of tickets sold.

r(n)=65n

If c= cost and n=number of tickets sold, then c(n) shows how cost (expenses of the concert promoter) depends on the number of tickets sold.

c(n)=4n+5500

Part 1: write an equation fir the profict function p(n). Show your work.

hint: profit =revenue- cost

Part 2: fine the profit for the concert promoter if he sells 850 tickets. Show your work and explain what your answer means in terms of the problem.

you would just plug in the formulas given to you following the hint it's:
r(n) - c(n)
which goes to
65n - (4n + 5500)
then we can simplify that to
61n - 5500
Part 2:
61(850) - 5500
51850 - 5500 = 46350
this means if he sells 850 tickets he will make a net of 46350 dollars

This problem will be solved by the hints given in the question.

Here it is: r(n) - c(n)

which goes to

65n - (4n + 5500)

simplify:

61n - 5500

Part 2:

61(850) - 5500

51850 - 5500 = 46350

The profit for the 850 tickets he sold was $46350
