To answer the first question, we have these two equations:
x + y = 500 and 7.5x + 4.5y = 2550
We can use substitution to solve for x and then plug it back into any equation and find y.
y = 500 - x
7.5x + 4.5 (500 - x) = 2550
7.5x + 2250 - 4.5x = 2550
3x = 300
x = 100 adults
100 + y = 500 → y = 400 students
To answer your second question, we have two new equations:
2x = y (This may be confusing, but since there were more student tickets sold, it is the larger number.)
x + y = 300
We can rewrite the first equation and add them together:
2x - y = 0
x + y = 300
3x = 300
x = 100 adults
100 + y = 300 y = 200 students
The money earned from these 300 people is 100 * 7.5 + 200 * 4.5 = 750 + 900 = $1650.
$2550 - $1650 = $900
The 300 tickets sold had a $900 fall in ticket sales.
Hope this helps!

Hello! I'm guessing you need someone to solve this equation!
4(5x-6)=2(8x+10)
20x-24=16x+20
Add 24 on both sides!
20x=16x+44
Subtract 16x on both sides!
4x=44
Divide 4 by 44
x=11
