In a baseball stadium 75% of seats are reserved for the public. The other seats are only for season-ticket holders at the 20,000 seats reserved for the public. How many total number of seats are in the stadium round your answer to the nearest whole number

If 75% of the seats are reserved for the public, then the remaining percentage for season ticket holders is 100% - 75% = 25%.

If 25% of the seats are reserved for season ticket holders, then 20,000 seats represents 25% of the total number of seats in the stadium.
Let's x be the total number of seats.
So, 0.25 * x = 20,000.
Therefore, x = 20,000 / 0.25 = <<20000/0.25=80000>>80,000.
Rounding to the nearest whole number, the total number of seats in the stadium is 80,000 seats. Answer: \boxed{80,000}.

To find the total number of seats in the stadium, we need to determine the percentage of seats that are reserved for season-ticket holders.

Given that 75% of seats are reserved for the public, the remaining percentage of seats for season-ticket holders is 100% - 75% = 25%.

Since the number of seats reserved for the public is 20,000, we can set up the following equation:

(25/100) * Total Number of Seats = 20,000

To solve for the total number of seats, we can rearrange the equation as follows:

Total Number of Seats = (20,000 * 100) / 25

Total Number of Seats ≈ 80,000

Rounding the answer to the nearest whole number, the total number of seats in the stadium is 80,000.
