Aconcert 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

The Given plane region is missing attached below is the plane region

answer : 24 π  or 75.40 sq. units

Step-by-step explanation:

Given data :

Height of plane region = 3

base of plane region  = 4

When we revolved the plane region completely we will we forming a cone hence we will calculate for the surface area of a cone

Radius of the new cone = 3

Height of the cone = 4

slant height of the cone ( l )  =  = 5

surface area of cone = πr^2 + πrl

                                   = π ( 3 )^2  + π (3 ) ( 5 )

                                   = 24 π  or 75.40 sq. units
