The price of a gallon of gas in one month was
$2.60. The following month, the price was $2.99.
What was the percent increase of the price of gas?
A 1.5% x
B 13% ?
C 15% ?
D 39% x
I need some help with this question, I know that its obviously not A or D, but I don't know how to solve it to figure out if its B or C.
299/260 = 1.15
so multiplied 260 by (1 + 0.15)
which is 100% + 15 %
Thanks Anon
You are welcome.
To find the percent increase of the price of gas, you can use the formula:
Percent Increase = (New Value - Old Value) / Old Value * 100
In this case, the old value is $2.60 and the new value is $2.99.
Substituting these values into the formula:
Percent Increase = ($2.99 - $2.60) / $2.60 * 100
Calculating this:
Percent Increase = $0.39 / $2.60 * 100
Percent Increase ≈ 0.15 * 100
Percent Increase ≈ 15%
Therefore, the correct answer is C, 15%.
