Question

The population of a mining town is 40,000. The mine closes, and 150 people leave the town each month. Which of the following correctly gives the number of people remaining in the town after three years?

a) 40,000 - 150 * 36

b) 40,000 - 150 * 3

c) 40,000 - 150 / 36

d) 40,000 - 150 / 3

Answer 1

The number of people remaining in the town after three years is 34,400.

Step-by-step explanation:

To find the number of people remaining in the town after three years, we need to calculate the number of people that leave the town each month for three years.

There are 12 months in a year, so for three years, there are 12 * 3 = 36 months.

Therefore, the correct expression to calculate the number of remaining people is: 40,000 - 150 * 36 = 34,400.
