Question

A towns population went from 25800 to 42600 in 15 years. What was the percent of change

Answer 1

165.1162791...%
To find this answer, I divided 42,600 by 25,800 and got 1.651162791... I then multiplied it by 100 to convert it into a percent and got 165.1162791...%

The "..." after the number means that the numbers continue to go on but are essentially unnecessary.

In conclusion, when you multiply 1.651162791... you get 42,600.

Answer 2

`\% Change = (|42600 -25800|)/(25800) x100 =65.116 \%`

Explanation:

The percent of change respect a reference value is given by the following formula:

`\% Change = (|Final -Initial|)/(Initial) x100`

On this case the initial value is 25800 and the final value 42600. So we can replace into the formula and we got:

`\% Change = (|42600 -25800|)/(25800) x100 =65.116 \%`

So then the increase respect the initial value is 65.116%, and makes sense since:

`1.65116 *25800 =42600`
