Question

The population, $$P ( t )$$ , in millions, of a country, in year $$t$$ , is given by the formula $$P ( t ) = 24 + 0.4 t$$ . What are the values of the population for $$t =$$ $$10,20$$ , and $$30 ?$$

A. $$30,33,36$$ millions

B. $$28,32,36$$ millions

C. $$24,28,32$$ millions

D. $$26,28,30$$ millions

For t = 10 years, $$P( 10) = 28 \text { millions}$$

For t = 20 years, $$P( 20) = 32 \text { millions}$$

For t = 30 years, $$P( 30) = 36 \text { millions}$$
