Tickets to a school play cost $3 for students and $8 for adults. On opening night, $1,000 was collected and 150 tickets sold.

Question

I don't know where to start on this question so I'm looking for help

Answer 1

3S + 8A = 1000

 

 S + A = 150 ---> A = 150 - S

 

3S + 8(150 -S) = 1000

 

3S + 1200 - 8S = 1000

 

1200 - 5S = 1000

 

-5S = -200

 

S = -200/-5 = 40

 

40 student tickets 

110 adult tickets

 

CHECK:

40*3 + 110 * 8 = 120 + 880 = 1000
