Answer:
A = number of adult tickets
S = number of student tickets
1033 = total tickets sold
A + S = 1033
5A = money collected for adult tickets
S = money collected for student tickets
2265 = total money collected
5A + S = 2265
two equations and two unknowns:
5A + S = 2265
A + S = 1033
subtract 2nd equation from 1st and solve for A:
4A = 1232
A = 308
Plug in value for A in 1st equation and solve for S:
A + S = 1033
308 + S = 1033
S = 725
