The graph shows the annual percent change in U.S. greenhouse gas emiss

Official Explanation

Pick the number 100 to represent the value of U.S. emissions in 1993. Then, in 1994, U.S. emissions were:

100+100*1.5% = 101.5

Next, the 1995 emissions were:

101.5+101.5*1.3% = 102.8195

The 1996 emissions were:

102.8195+102.8195*3.2% = 106.109724

So, rounded to two decimal places, emissions in 1996 were 106.11% of emissions in 1993. Note that it’s best not to round until the very end in a question like this.

The correct answer is (E).

You did much of the work already in Question I above when you calculated that, if emissions in 1993 were 100, then emissions in 1996 were 106.1097. Now, let the 1993 emissions be x percent of the 1996 emissions. Thus:

100=x%(106.1097)

\(x=\frac{100}{106.1097}(100)\)

\(x=94.24\)

The correct answer is (B).
