Question

The population of the town is given by the function y = 60,000 - 500x, where y is the number of inhabitants and x is the time in years. What is the population of the town after 9 years?

Answer 1

The answer would be 55,500.

Take a look at the function: y = 60,000 - 500x.

- 500 (x) indicates that by each year the population of the town will decrease by a total of 500 residents.

So after 9 years, 4,500 residents should no longer be residing there.

To figure this out,

Multiply 9 and 500, which as a result you should get 4,500.

Then subtract 4,500 from 60,000.

The ending result would be 55,500.

Answer:

The population of the town after 9 years would be 55,000 residents.

Hope this helped,
