We should expect the population to reach 71000 in 1993.

Step-by-step explanation:

If the population will double every 54 years and the population in 1974 was 56000 people, then the function that represents this situation is

$y=56000\cdot 2^{\frac{x}{54}},$

where x is time in years since 1974.

Nota that in 1974, x=0, then y=56000 and after 54 years the population will be $y=56000\cdot 2^{\frac{54}{54}}=56000\cdot 2=112000.$

Therefore, you have to calculate x, when y=71000:

$71000=56000\cdot 2^{\frac{x}{54}},\\ \\\dfrac{71}{56}=2^{\frac{x}{54}},\\ \\\dfrac{x}{54}=\log_2\dfrac{71}{56},\\ \\x=54\log_2\dfrac{71}{56}\approx 18.49$

Thus, we should expect the population to reach 71000 in 1993 (after full 19 years).
