Question

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 thousand jobs per year from 2008 to 2018. Assuming this holds true, what will be this industry’s percent change from 2008 to 2018? a. 70% b. -27% c. -17% d. -75%

Answer 1

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.

Answer 2

Answer:

The answer is B just took the test on edge. Hope this helps in some formality.
