Answer:
The correct answer is 2030.
Step-by-step explanation:
To start we must analyze the information we have.
We know that a city has 8000 inhabitants and that each year this number increases by 0.5%. That means that <u>each year it has 40 more inhabitants</u>:
(8000 . 0,5) : 100 = 40
Having this information we could do a cross multiplication:
1 year ------- 40 inhabitants
x years ------- 81200
81200 = 40.x
x = 81200 : 40
x = 2030
In this way we can verify that the correct answer is 2030.

Answer:
-5/12
Step-by-step explanation:
-1 times 1 is -1 so -1/3
2 times 2 is 4 so 4/5
-1/3 divided by 4/5

-1/3 times 5/4
-1 times 5=-5
3 times 4=12
so the final answer is -5/12
