Given the initial price and the increased price of the same item, the percentage increase in the price of the item is 21%.
Percentage increased is expressed mathematically as;
C = ((x₂ - x₁) / x₁)100%
Where x₁ is initial value and x₂ is new value.
Given the data in the question;
We substitute the given values into the equation above.
C = ((x₂ - x₁) / x₁) × 100%
C = ((2.6 - 2.15) / 2.15) × 100%
C = ( 0.45 / 2.15) × 100%
C = ( 0.2093) × 100%
C = 21%
Given the initial price and the increased price of the same item, the percentage increase in the price of the item is 21%.
