Question 1152852
.
<pre>
Let x be the number of the Lower box tickets.

Then the number of the Upper box tickets is (164-x).


The equation for the total is


    12.50x + 10*(164-x) = 1945.00.


It is your basic equation to find the value of x.


From the equation


    x = {{{(1945-10*164)/(12.50-10)}}} = 122.


<U>ANSWER</U>.  122 Lower box tickets and the rest, 164-122 = 42 Upper box tickets.


<U>CHECK</U>.  122*12.50 + 42*10.00 = 1945 dollars.    ! Precisely correct !

Solved.
