Question 204124
Let S = the number of student tickets sold. Then 1500-S = the number of non-student tickets sold.
The cost of tickets can be expressed as:
Students: $8(S)
Non-students: $10(1500-S) The sum of these two amounts is given as $12,300. In equation form, you can write:
8S+10(1500-S) = 12300 Solve for S.
8S+15000-10S = 12300 
-2S+15000 = 12300 Subtract 15000 from both sides.
-2S = -2700 Divide both sides by -2
S = 1350
1,350 student tickets were sold.
