Hey there!
To answer this problem, you'll need to know how to convert a percentage into a decimal. You will move the decimal point of a percentage to the left twice to get the decimal version. If there isn't a decimal, remember that 26, for example, is the same at 26.0.
6.5% = 0.065
(It's not equal to 0.65, since that would be the same as 65.0%).
So, now you have to multiply that decimal by 8,600. Then, you'll add the number you get to get your final answer.
8600 * 0.065 = 559
8600 + 559 = 9159
9,159 will be your final answer.
Hope this helped you out! :-)
