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?
A
150% increase
B
120% increase
C
136% increase
D
77% increase
To find the percent of change, we can use the formula:
Percent of change = (Final value - Initial value)/Initial value * 100%
In this case, the initial value is $1.51 and the final value is $3.57.
So the percent of change = (3.57 - 1.51)/1.51 * 100% = 1.06/1.51 * 100% ≈ 70.2%
Therefore, the percent of change is approximately a 70.2% increase.
