How many lower level tickets were sold?
How many upper level tickets were sold? Answer by greenestamps(13200) (Show Source):
Let x be the number of lower level tickets and y be the number of upper level tickets. Then the given information tells us
(1) x+y = 6481 (the total number of tickets was 6481)
(2) 67x+73y = 461383 (the total cost of the tickets was 461383)
With both equations in Ax+By=C form, the easiest way to solve the pair of equations is by elimination.
--> multiply equation (1) by 67
--> subtract that new equation from equation (2), eliminating x
--> solve the resulting equation for y
--> substitute that value of y in equation (1) to solve for x
