Question

the price of a gallon of unleaded gas was $2.79 yesterday. today, the price rose to $2.85 . find the percentage increase. round your answer to the nearest tenth of a percent.

Answer 1

Yesterday = $2.79
Today =     $2.85

% Increase =      ((2.85 - 2.79) / 2.79)  * 100%
   
                     =   (0.14/2.79)   * 100%
 
                     ≈       0.0501 * 100%
  
                     ≈ 5.01 %

                    ≈ 5.0 %   to the nearest tenth.

Answer 2

Answer:

2.2%

Step-by-step explanation:

We first find how much the price increased from yesterday.

Amount of increase: $2.85- $2.79 = $0.06

To find the rate of increase, we divide the amount of increase by yesterday's price.

Rate of increase: $0.06/$2.79 = 0.0215

We convert this rate to a percentage by multiplying it by .

Percentage increase: (100x0.0215)%= 2.15%

Rounding to the nearest tenth of a percent, we get : 2.2%

FINAL ANSWER : 2.2%
