Question

If a city with a population of 150,000 doubles in size every 34 years, what will the population be 68 years from now?

Answer 1

Answer:

In 68 years, the population will be 600,000

Step-by-step explanation:

Population of the city is 150000

It doubles every 34 years, that is 34 years from now, it will be

150000 × 2 = 300000

In 68 years, which is another 34 years, it will be double of 34 years or 4 times the original population, that is

300000 × 2 = 600000, or

150000 × 4 = 600000
