the addTenPercent method should increase the value of anything that is passed to it by 10% 1. you have hard coded the value 9 in line 11, you should use the variable ' i ' 2. in line 11, integers are used for the operation but the answer is stored in a double, the program will perform the operation but will store the answer without the decimal part in the double variable 3. even after adjusting the operators to be double, the formula used is incorrect, it converts 9 to 10.11.., the answer here should be 9.9

The correct output to the method should be 9.9 when passed 9 as an argument. Your code spits out 9. The problem is that you are using integers in your calculation instead of doubles. The number is cast to a double after the calculation completes. to fix this try using numbers that include a decimal and a zero (Ex: 10.0 instead of 10). The compiler will recognize the numbers as doubles and correctly calculate fractions of whole numbers then. You still have a math error to figure out, as your code prints out 10.1111111 after applying this. A couple correct formulas to apply (choose one) are: number + (number * 10%) or number * 110%
