Suppose the population of a certain city is 5831 thousand. It is expected to decrease to 5204 thousand in 50 years. Find the per

SVEN [57.7K]

Answer:

The percent decrease is approximately $10.75\%$

(Don't know what you are expected to round to.)

Step-by-step explanation:

Percent change can be calculated by doing:

$\frac{\text{original}-\text{new}}{\text{original}}$

Then you multiply the result to covert it to a percentage.

Let's use this formula:

$\frac{5831 \text{thousand}-5204 \text{ thousand }}{5831 \text{thousand}}$

$\frac{\text{thousand}}{\text{thousand}} \cdot \frac{5831-5204}{5831}$

$\frac{5831-5204}{5831}$

$\frac{627}{5831}$

$0.1075$ approximately

Now the answer as a percent is $10.75\%$ approximately.

The percent decrease is approximately $10.75\%$
