This is a price increase because the final price is greater than the initial price. The price increase from 10 to 12 is equal to 20%.
In Mathematics and Euclidean Geometry, a percentage refers to any number that is expressed as a fraction of hundred (100).
Based on the information provided above, we can logically deduce the following;
Initial price (before) = 10
Final price (after) = 12
Therefore, this is a price increase because the final price is greater than the initial price.
Mathematically, percentage increase can be calculated by using the following mathematical equation:
Percentage price increase = (Final value - Initial value)/Initial value × 100
Percentage price increase = (12 - 10)/10 × 100
Percentage price increase = 2/10 × 100
Percentage price increase = 20%.
Complete Question;
Price increase/decrease? before: 10 after: 12.
