Respuesta :

To find the percent of a number, you first need to convert the percentage to decimal form...
15%= 0.15

Then you multiply the decimal by the number you need to find the percentage of...
0.15 x 85= 12.75

So your answer is 12.75

10% of 85 = 8.50
5% of 85 = 8.50/2 = 4.25

15% = 10% + 5% = 8.50 + 4.25 = 12.75

OR

(Amount / total percentage) * percentage wanted = answer

(85/100)*15 = 12.75
