The percentage increase is worked out by taking the difference between the original amount and the final amount, and then dividing that difference by the original amount. This is a simple calculation that requires just a basic calculator. A writing utensil and scratch paper may be useful for recording your results.
Know MoreFind the difference between the starting amount and the final amount. For example, if the original amount was 20 and the new number is 28, you would perform the following calculation: 28 - 20 = 8. You should always get a positive number. If the number is negative, then there is either a decrease in the two amounts or you used the incorrect amount.
Divide the difference of the two numbers by the original. This usually produces a decimal, unless the increase is a factor of the original value. For example, if you were to use the numbers from the previous step, the process would look like this: 8 / 20 = 0.40.
Multiply the decimal number by 100 to get the percentage increase. Using the same numbers as in the previous examples, 0.40 x 100 = 40 percent. Remember to keep the decimal spaces consistent throughout your calculations.
Formulas and functions are both important tools when creating an Excel spreadsheet; while users type formulas right into the bar at the top of the spreadsheet, formulas come built within the application itself, so it actually comprises a special sort of formula. While it is not possible to nest a formula in Excel, it is possible to do so with functions.
Full Answer >In mathematics, a variable is a symbol used for a number not yet known, while a constant is a number or symbol that has a fixed value. The value of a variable can change depending on the equation, while the value of a constant always remains the same.
Full Answer >The graph of a linear equation forms a straight line, while a non-linear equation's graph does not form a straight line.Most equations can be graphed on a Cartesian coordinate plane using the variables x and y.
Full Answer >A relation is a set of numbers that have a relationship through the use of a domain and a range, while a function is a relation that has a specific set of numbers that causes there to be only be one range of numbers for each domain of numbers. All functions are relations, but all relations are not functions.
