The price of a gallon of unleaded gas has dropped to $2.84 today. Yesterday’s price was $2.90. Found the percentage decrease. When your answer to the nearest 10th of a percent?

Sagot :

To find the percentage decrease we need to subtract yesterday's price - the current price

Current price 2.84

yesterday price 2.90

2.90 - 2.84 = 0.06

This is the difference in prices

So to find the percentage we divide the difference with yesterday's price

0.06 / 2.90 = 0.0206

We multiply that value by 100 to get the final percentage

0.020 * 100 = 2.06

Finally, we take the answer to the nearest 10th

Answer = 2.1

This is because 6 is bigger than 5 so we take the Tenths position to 1.
