.
250 tickets to a show were sold,some at 200 and others at R300
the total amount of money taken for the show was R57 500
how many R200 tickets and how many R300 tickets were sold
~~~~~~~~~~~~~~~~

Let x be the number of R300 tickets.

Then the number of the R200 tickets is (250-x).


Write the revenue equation (the total money equation)

    300x + 200*(250-x) = 57500.


Simplify and find x

    300x + 200*250 - 200x = 57500

           100x           = 57500 - 200*250

           100x           =     7500

              x           =     7500/100 = 75.


ANSWER.  75 tickets at R300  and the rest  250-75 = 175 tickets at R200.


CHECK.   75*300 + 175*200 = 57500,  total money.   ! correct !
