The population of Cuba is 1.3 million. The country's population is expected to grow at a rate of 4% each year.

The population of Cuba will be

million in 10 years.

The population growth will be modeled using exponential growth:

f (x) = a (b) ^t

where:

a=initial value

b=growth rate

thus plugging in the values we get:

f (x) = 1.3 (1.04) ^t

thus the population after 10 years will be:

f (x) = 1.3 (1.04) ^10

f (x) = 1.9243

thus the population in 10 years will be:

1.9243 million
