Question

Quizplus · Accepted Answer

The figure shows that in 1990, Portland's greenhouse gas emissions were at 8.61 million metric tons of CO2 equivalent. In 2012, the emissions were reduced to 6.4 million metric tons of CO2 equivalent. To calculate the percentage change, we use the formula: 
Percentage change = ((final value - initial value) / initial value) * 100
Plugging in the numbers, we get:
Percentage change = ((6.4 - 8.61) / 8.61) * 100 = -25.7%
Rounding to the nearest whole number, the answer is 26%, which is choice C.
