Solution:

Let the number of second shift workers = x
So, the number of first shift workers =\(\frac{ 2}{3x}\)

Production by each first shift worker = y
Production by each second shift worker=\( \frac{4}{3y}\)

By bringing the above knowledge together, we can form an equation

Total =\(\frac{2}{3}\)xy +\(\frac{4}{3}\)xy

We can get 2xy +\( \frac{4}{3}\)xy = 2xy

Now, we can look for the values for the total production by the first shift workers, which will be 12 among the options available. And when we put that into the equation, we get 12 +\( \frac{4}{3}\)yx

12 + \(\frac{2}{3} \)xy2 = 36(total)

Hence, Total production by first shift workers = 12, and the Number of total light bulbs made by the two shifts = 36

At a certain factory, the number of first-shift workers is 2/3 the number of second-shift workers. Every day, each second-shift worker can make 4/3 as many light bulbs as each first-shift worker.

In the first column, identify a possible number of total light bulbs made on one day by the two shifts combined; in the second column, identify the corresponding number of total light bulbs that the first-shift workers made on the same day. Make only two selections, one in each column.
