Question

the utility industry has 428.5 thousand jobs in 2010 and is expected to decline at an average rate of 3 thousand jobs per year from 2010 to 2020 assuming this holds true what will be the utilities percent change for 2010 to 2020​

Answer 1

Answer: 7%

Step-by-step explanation:

Given: Initial jobs = 428.5 thousand

Average rate of declining of jobs  from 2010 to 2020 =  3 thousand jobs per year

From 2010 to 2020 , there are 10 years.

Total jobs declines till 2020 = 10 x (3 thousand)

= 30 thousand  (Change in jobs)

Now, utilities percent change for 2010 to 2020​ : $\dfrac{change \ in \ job\ numbers}{Initial\ jobs}\times 100$

$=\dfrac{30}{428.5}\times100\\\\\approx7.00\%$

Utilities percent change for 2010 to 2020 = 7 %
