Problem Analysis

To solve this problem, we need to determine the total number of light bulbs that were delivered to the store. We are given that 12 light bulbs were broken, which represents 3% of the total. We need to find the total number of light bulbs.

Solution

Let's assume the total number of light bulbs delivered to the store is x.

We are given that 12 light bulbs were broken, which represents 3% of the total. We can set up the following equation:

3% of x = 12

To solve for x, we can convert 3% to a decimal by dividing it by 100:

0.03x = 12

Now we can solve for x by dividing both sides of the equation by 0.03:

x = 12 / 0.03

Let's calculate the value of x:

x = 400

Therefore, the total number of light bulbs delivered to the store is 400.

Answer

The store received a total of 400 light bulbs.
