One hundred twenty-five tickets have been sold for an event at a local theater. If this represents 25% of the capacity for the theater, which of the following is the capacity?

A. 156 B. 375 C.410 D. 500

0.25x = 125

x = 125/0.25

x = ??

500

To find the capacity of the theater, we can set up a proportion using the given information.

Let's assume the capacity of the theater is "x". We know that 125 tickets represent 25% of the capacity.

25/100 = 125/x

Now, we can solve for "x" by cross-multiplying:

25x = 125 * 100
25x = 12500

To isolate "x", we divide both sides of the equation by 25:

x = 12500/25
x = 500

Therefore, the capacity of the theater is 500.

So, the correct answer is D. 500.
