Question

a comedy show sells lower level tickets for $78 and upper level tickets for $59. on the opening knight 2368 tickets were sold for total and $157800

Answer 1

let L represent lower level tickets and U upper level.

Starter equations:
L + U = 2368
78L + 59U = 157800

Solve simultaneous equations:
59L + 59U = 139712
so 19L = 18088
L = 952
U = 2368 - 952 = 1416

952 lower level tickets and 1416 upper level tickets were sold.
