Add or subtract a percentage from a number or solve the equations. (i) If a number is increased by x %, then the new number = (1 + x/100) given number. 10% increase of the number 50 The formula is given by: Bonus Example: Mark is buying a sweater that costs $15. For example, you may need to find out what percent 10 is of 100. Examples Example 1) Find 27% of $50. Example: For a $54 bill, 10% is $5.4. X) X becomes Y X = P%, which is the same as P% = Y X, Solution: Solve for P% using the percentage formula, The 'what' is X that we want to solve for, Divide both sides by P% to get X on one side of the equation, Y P% = (P% X) P% becomes Y P% = X, which is the same as X = Y P%, Solution: Solve for X using the percentage formula, (P% X) P% = Y P% becomes X = Y P%, Multiply both sides by X to get X out of the denominator, Divide both sides by P% so that X is on one side of the equation, Y P% = (P% * X) P% becomes Y P% = X, Multiply both sides by X to get Y on one side of the equation, Convert decimal to percent by multiplying by 100. In this lesson, we learn how to find the percentage of a whole number.
