Problem Analysis

To solve this problem, we need to find the total number of light bulbs in the box given that there are 12 risky light bulbs, which represents 4% of all the light bulbs. We can use this information to calculate the total number of light bulbs in the box.

Solution

Let's assume the total number of light bulbs in the box is x.

According to the problem, 12 risky light bulbs represent 4% of all the light bulbs. Mathematically, we can represent this as:

12 = 0.04 * x

To find the value of x, we can rearrange the equation:

x = 12 / 0.04

Now, let's calculate the value of x:

x = 300

Therefore, there were 300 light bulbs in the box.

Answer

There were 300 light bulbs in the box.
