8 0

$4(2 - 5x) = 6 - 3(1 - 3x) \\ 8 - 20x = 3(1 - 3x) \\ 8 - 20x = 3 + 9x \\ subtract \: 9x \: from \: bth \: sides \\ 8 - 29x = 3 \\ subtract \: 8 \: from \: both \: sides \\ - 29x = - 5 \\ divide \: - 29 \: both \: sides \\ x = \frac{5}{29}$
answer is C

Galina-37 [17]

Let $p=$ the price of a ticket
Let $c=$ the cost to put on the show

Formula:
(profit) = (ticket price) * (number of people) - (cost to put on show)
We have two equations here:
$500=120p-c$
$400=100p-c$
Solve:
$100=20p$
⇒ $p=5$
⇒ $400=100(5)-c$
⇒ $400=500-c$
⇒ $c=100$

So the price of a ticket is $5, and the cost to put on the show is $100.
