Say a certain manufacturing industry has 63.1 thousand jobs in 2008, but is expected to decline at an average annual rate of 1.7

kenny6666 [7]

If the industry is losing 1.7 thousands jobs in one year, in 10 years it will then lose 1.7*10, or 17 thousand jobs.

now, if we take 63.1 to be the 100%, how much is 17 in percentage off of it?

$\bf \begin{array}{ccllll}
amount&\%\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
63.1&100\\
17&x
\end{array}\implies \cfrac{63.1}{17}=\cfrac{100}{x}$

solve for "x", round it up, make it negative, since it should be a negative rate, since is a decrease in the initial amount.
