Question
The price of a gallon of unleaded gas was 2.86. Find the percentage increase. Round your answer to the nearest tenth of a percent.
Solution
Sure, here are the steps to find the percentage increase:
-
First, find the difference in price. Subtract the original price from the new price. So, 2.81 = $0.05.
-
Next, divide the difference by the original price. So, 2.81 = 0.01779.
-
To convert this to a percentage, multiply by 100. So, 0.01779 * 100 = 1.779.
-
Finally, round to the nearest tenth of a percent. So, the percentage increase is approximately 1.8%.
