Answer:
x = 5 and y = 1 is the answer.
Step-by-step explanation:
(-5)(x+4y=1)
(-4)(-3x-5y=-10)
-5x + -20y = -5
12x + 20y = 40
———————
7x + 0 = 35
7x= 35
7x/7 = 35/7
x = 5
subtitution:
x= 5
x + 4y = 1
5 + 4y = 1
4y = 1 - 5
4y = 4
4y/4 = 4/4
y = 1
Answer: 565 general admission and 430 lower-level seating tickets sold (Answer (D))
Steps:
Let x be the number of general admission tickets, and y be the number of lower level tickets.
Set up the two equations:
68762.5 = x * 47.50 + y * 97.50 (total price as a sum of individual volumes)
x + y = 995 (sum of individual count = total count of tickets sold)
solve for x, y:
x = 995 - y
plug into the first equation:
68762.5 = (995-y) * 47.50 + y * 97.50
solve for y:
y = 430
then x = 565
x = 565 and y = 430
