A population of 1,200 decreases to 1,080. What is the percent decrease?

Question

A
10%
B
15%
C
5%
D
12%

Answer 1

To find the percent decrease, you can use the formula:

\[ \text{Percent Decrease} = \left(\frac{\text{Original Value} - \text{New Value}}{\text{Original Value}}\right) \times 100 \]

In this case, the original value is 1,200 and the new value is 1,080.

\[ \text{Percent Decrease} = \left(\frac{1200 - 1080}{1200}\right) \times 100 \] \[ = \left(\frac{120}{1200}\right) \times 100 \] \[ = 0.1 \times 100 \] \[ = 10% \]

Therefore, the percent decrease is 10%.

So the answer is A.
