The national average cost for gas in the year 2000 was $1.51 a gallon. Currently, the average for a gallon of gas is $3.57. What is the percent of change?
The percent of change is given by the formula:
percent of change = (new value - initial value) / initial value * 100
In this case, the new value is $3.57 and the initial value is $1.51. Substituting these values, we get:
percent of change = (3.57 - 1.51) / 1.51 * 100
Simplifying this expression, we get:
percent of change = 2.06 / 1.51 * 100
percent of change ≈ 136.42
Therefore, the percent of change for gas prices from 2000 to the present is approximately 136.42%.
