Find the percent of increase to the nearest whole from 12 to 20

ankoles [38]

Answer:

The answer is

Step-by-step explanation:

To find the percentage increase we use the formula

<h3> $Percentage \: change = \frac{change}{original \: \: quantity} \times 100\%$ </h3>

From the question

The original value = 12

To find the change we subtract the smaller value from the larger one

That's

Change = 20 - 12 = 8

So the percentage increase is

<h3> $\frac{8}{12} \times 100 \%\\ = \frac{2}{3} \times 100\% \\ = 66.67\%$ </h3>

We have the final answer as

$67\%$ to the nearest whole number

Currently, there are 1,460 wolves in Scataway National Park. If the population of wolves is growing at a rate of 6% every year,

VARVARA [1.3K]

Answer:

$P(t) = 1460(1.06)^t$

Step-by-step explanation:

Exponential equation for population growth:

The exponential equation for a population after t years is given by:

$P(t) = P(0)(1+r)^t$

In which P(0) is the initial population and r is the growth rate, as a decimal.

Currently, there are 1,460 wolves in Scataway National Park.

This means that $P(0) = 1460$

Growing at a rate of 6% every year:

This means that $r = 0.06$ . So

$P(t) = P(0)(1+r)^t$

$P(t) = 1460(1+0.06)^t$

$P(t) = 1460(1.06)^t$
