Adult tickets to a a basketball game cost $5. Student tickets cost $1. A total of $2,757 was collected on the sale of 1,185 tick
Anastaziya [24]

Answer:

Number of Adults Ticket=393

Number Of Students Tickets=792

Step-by-step explanation:

Let 'x' be the Adult's tickets

Let 'y' be the Student's tickets

x+y=1185 (total sold tickets)

5x+y=2757(total cost of tickets)

-(5x+y=2757)x+y=1185

 (-5x-y)- x+y=1185-2757

=-4x+0 = (-1572)

=-4x=(-1572)

x= (-1572)÷-4

=393

=x+y=1185

=393+y=1185

=y=792

So Number of Adults Ticket=393

Number Of Students Tickets=792
