Question 1096650: Last Tuesday Regal Cinemas sold a total of 8500 movie tickets. Proceeds totalled $64600. Tickets can be bought in one of the three ways. A matinee admission costs $5, student admission is $6 all day, regular admissions are $8.50. How many of each type were sold if twice as many student tickets were sold as matinee tickets?

You can put this solution on YOUR website!
r = number of regular tickets
s = number of student tickets
m = number of matinee tickets

r + s + m = 8500
8.5r + 6s + 5m = 64600
s = 2m

Plug the third equation (s = 2m) into the other equations.

r + 3m = 8500
8.5r + 17m = 64600

You can use any method (substitution, elimination, graphing) to solve for r and m. Plug those values back into the first equation and you are done.

            It is a typical problem to be solved using only one single unknown.


Let x be the number of the matinee tickets.

Then the number of the student tickets is 2x,

and the number od the regular admission tickets is  (8500-x-2x) = (8500-3x).


Now you write the total money equation (the revenue)


    5x + 6*(2x) + 8.50*(8500-3x) = 64600  dollars.


Simplify and solve for x


    5x + 12x - 8.50*3*x         = 64600 - 8.50*8500


         x                      = %2864600+-+8.50%2A8500%29%2F%285%2B12-8.50%2A3%29 = 900.


ANSWER.  900 matinee tickets;  2*900 = 1800  student tickets  and the rest, 8500-900-1800 = 5800, were the regular admission tickets.


CHECK.  900*5 + 1800*6 + 5800*8.50 = 64600 dollars, in total.    ! Correct !

Solved.

From my post, learn how to solve such problems using one single unknown variable, only.

It is the major lesson to learn from my solution.
