Your school drama club is putting on a play and hopes to raise $600 from ticket sales. They sell adult tickets for $8 each and student tickets for $5 each. Let x represent the number of adult tickets and y represent the number of student tickets. The equation to represent the number of tickets sold to reach their goal, 8x+ 5y = 600, is graphed below. If 40 adult tickets are sold, how many student tickets must be sold to reach their goal?

Question

ganpat · Answer

adult ticket = x
student ticket = y

8x + 5y = 600
given , x = 40

8 (40) + 5y = 600

5y = 600 - 320 
5y = 280
y = 56...

Students tickets sold...
