A concert venue sold 8000 tickets for a total revenue of 250,000. VIP tickets cost 50 and popular stand tickets cost $30. How many of each type of ticket were sold?

Let $V$ be the number of VIP tickets sold and $P$ be the number of popular stand tickets sold.
We are given:

• Total number of people: 8000
• Price of VIP ticket: \50$
• Price of popular stand ticket: \30$
• Total revenue: \250,000$

From this, we can form two equations:

$$V + P = 8000 \quad \text{(Equation 1)}$$ $$50V + 30P = 250000 \quad \text{(Equation 2)}$$

$$50V + 30(8000 - V) = 250000$$ $$50V + 240000 - 30V = 250000$$

$$20V + 240000 = 250000$$ $$20V = 250000 - 240000$$ $$20V = 10000$$ $$V = \frac{10000}{20}$$ $$V = 500$$

$$P = 8000 - V$$ $$P = 8000 - 500$$ $$P = 7500$$

The number of VIP tickets sold is 500 and the number of popular stand tickets sold is 7500.

$$\boxed{\text{VIP tickets: } 500, \text{ Popular stand tickets: } 7500}$$
