Let A = number of adult tickets and S = number of senior tickets.
The total number of tickets is 444. This equals A + S.
444 = A + S
Total receipts were $7345. This can be represented as:
7345 = A*20 + S*15
Solve for A in first equation.
A = 444 - S
Substitute this into the 2nd equation for A
7345 = (444 - S)*20 + S*15
Solve for S
7345 = 8880 - 20*S + 15*S
7345 = 8880 - 5*S
-1535 = -5*S
307 = S
Therefore there were 307 senior tickets sold.
The number of adult tickets would be 444-307 = 137
