On January 1st 2020 the populations of Japan and the Philippines were 126.5million and 109.6 respectively. Japan's population is currently decreasing by 0.2% per year while the population of the Philippines is increasing by 1.6% per year. If these rates of change remain constant, during which year will the two population be the same​

Respuesta :

Well that will happen I’m not sure I think 2040

In 422.5 years, the two populations will be the same

Let the year when the two populations will be the same be represented by x.

The equation to solve the question will be:

126.5 - 0.2x = 109.6 - 0.16x

Collect like terms

0.2x - 0.16x = 126.5 - 109.6

0.04x = 16.9

x = 16.9/0.04

x = 422.5

In conclusion, in 422.5 years, the two populations will be the same.
