Answer:

Kindly check explanation

Step-by-step explanation:

Given the following :

Number of Green jobs in Hawaii (2010) = 11,145 ; equivalent to 2.4% of total private employment

Projected increase by 26% between 2011 and 2012

(a) How many total jobs were there in the private sector in Hawaii in 2010?

2.4% = 11,145

100% = x

0.024x = 11,145

x = 11,145 / 0.024

x = 464,375

Total private employment in Hawaii (2010) = 464,375

B) How many green jobs in the private sector were expected by 2012?

Projected increase in green jobs by 26%

Present number of green jobs = 2.4%

Hence, by 2012, the total percentage = (26+2.4)% = 28.4%

2.4% = 11,145

28.4% = x

0.024x = (0.284 × 11,145)

0.024x = 3165.18

x = 3165.18 / 0.024

x = 131,882.5

(C) If the overall job market was projected to increase by 4.3%, what percentage of total private-sector jobs was projected to be green by 2012?

Increase of 4.3% in overall job market :

104.3% × 464,375

1.043 × 464,375 = 484,343.125

Percentage projected to be green by 2012:

(Projected number of green jobs in 2012 / projected number of total employment) × 100%

(131,882.5 / 484,343.125) × 100%

0.2722914 × 100% = 27.23%

Answer:

The answer is below

Step-by-step explanation:

a) Given that Green jobs in the private sector in Hawaii were estimated at 11,145 in 2010 representing 2.4% of total private employment.

Let x represent the total jobs in the private sector in Hawaii in 2010. Hence:

2.4% of x = 11145

0.024 × x = 11145

x = 11145/0.024

x = 464375

The total jobs in the private sector in Hawaii in 2010 was 464375 jobs.

b) The number of green jobs was expected to increase by 26% between 2010 and 2012.

The number of green jobs in 2010 was 11145, therefore:

The increase in green jobs from 2010 and 2012 = 26% × 11145 = 0.26 × 11145 = 2898 jobs

Therefore the number of green jobs in the private sector that was expected by 2012 = 11145 + 2898 = 14043 jobs

c) Since there was a projected increase of 4.3%:

The number increase of total private-sector jobs projected in 2012= 4.3% × total jobs in the private sector in Hawaii in 2010 = 0.043 × 464375 jobs = 19969 jobs

Projected total jobs in the private sector in Hawaii in 2012 = 464375 + 19969 = 484344

percentage of total private-sector jobs was projected to be green by 2012 = number of green jobs in the private sector expected by 2012 / Projected total jobs in the private sector in Hawaii in 2012 × 100% = 14043/ 484344 × 100%

percentage of total private-sector jobs was projected to be green by 2012 = 2.9%
