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?
To calculate the percent change between the two prices, we use the formula:
Percent Change = ((Current Price - Original Price) / Original Price) * 100
Plugging in the values:
((3.57 - 1.51) / 1.51) * 100 = (2.06 / 1.51) * 100 = 1.3649 * 100 = 136.49%
Therefore, the percent change in the cost of gas from the year 2000 to the current year is 136.49%.
