Question

The table below shows the relative investment in alternative energy sources by type. One column shows the relative investment in 2007 of $75milliontotalinvestedinalternativeenergy.Theothercolumnshowstheprojectedrelativeinvestmentin2017givencurrenttrends.Thetotalprojectedinvestmentinalternativeenergyin2017is$254 million.

	Actual 2007 Investment	Projected 2017 Investment
Biofuels	0.310	0.34
Wind	0.40	0.32
Solar	0.27	0.30
Fuel Cells	0.02	0.04
Toatl	1.00	1.00

Based on the information in the table, which of the following statements is the most accurate?

• A. The value of the 2007 investment in bio fuels was approximately $50 million.
• B. The portion of total alternative energy investment focused on wind sources is projected to decrease by 8% in 2017.
• C. The dollar amount invested in fuel cells in 2007 is projected to double in 2017.
• D. The top three types of alternative energy were invested in more equally in 2007 than they are projected to be in 2017.

Answer 1

The correct option is B The portion of total alternative energy investment focused on wind sources is projected to decrease by 8% in 2017.

As per given relative investment in $2007$ of $\$75$ million for alternative energy

And The projected investment in $2017$ is $\$254$ million For alternative energy

(A) Given investment in bio fuels $2007$ is $0.310$, then total investment $=$ $0.310\times 75=$23.25$ million

So the value of the $2007$ investment in bio fuels was approximately $\$50$ million is wrong.

(B)The investment in wind sources is $0.40$ and $2017$ is $0.32$.

Then the total alternative energy investment focused on wind sources is projected to decrease $=0.40-0.32=0.08$

In $\%=$ $0.08\times 100=8$

Then (B) is most accurate
