Question

The Wall Street Journal reporter the biggest music comeback in 2014 was vinyl records. Nearly 8 million vinyl were sold in 2014, mostly to younger markets. If there were 15 vinyl record factories pressing records in the United States in 2014, and only 2/3 remain operational in 2015, how many factories closed down?

Answer 1

5 factories closed

Explanation:

In 2014 there were 15 operating factories.

We know that of those 15 factories only 2/3 remain operative.

If only 2/3 remain operational this means that 1/3 of them closed.

To calculate the number of factories that closed we must multiply the initial number of operative factories by 1/3.

This is:

`15 * (1)/(3) = (15)/(3) = 5`.

5 factories closed
