A town’s population went from 35,000 to 42,000 in 3 years. What was the percent of change?

dolphi86 [110]

Answer:

The population changed by 20% in 3 years

Step-by-step explanation:

The percentage change, is given by the following equation;

$Percentage \ change = \dfrac{Final \ value - Initial \value }{Initial \ value} \times 100$

The given parameters are;

The initial population of the town = 35,000

The final population of the town = 42,000

The percentage change in the population is therefore;

$Percentage \ change \ in \ population= \dfrac{42,000 - 35,000 }{35,000} \times 100 = 20 \%$

The population changed (increase) by 20% in 3 years.

From the set 1/2/3/4/5 which values make the inequality n + 1 > true?

saul85 [17]

Hi there!

To make n+1>4 true, you must have n be a numebr greater than 3...

The reason why is because if it is less than 3 or 3, it’ll have to be <.

The two numbers that can make this equation true is 4 and 5...

$4+1=5>4$

$5+1=6>4$

And if it is 1,2, and 3 it would be:

$1+1=2$

$2+1=3$

$3+1=4=4$
