To find the capacity of the theater, we need to determine what number corresponds to 100% when 125 tickets represent 25%.

Let's set up a proportion:
25% (125 tickets) = 100% (capacity)

We can solve this proportion by cross-multiplication:
25% * capacity = 100% * 125 tickets

To do this, we need to convert the percentages to decimals:
25% = 25/100 = 0.25
100% = 100/100 = 1

0.25 * capacity = 1 * 125

Now, isolate 'capacity' by dividing both sides of the equation by 0.25:
capacity = (1 * 125) / 0.25

Simplifying the equation on the right-hand side:
capacity = 125 / 0.25

Using division:
capacity = 500

Therefore, the capacity of the theater is 500.

So, the answer is D. 500.
