23 percent plus 15 percent is 38 percent. However, this only works if the percents are of the same thing.
20 plus 15 percent = 23
20 * 1.15 = 23
23 plus 69 plus 13 plus 3 percent of 100 percent = 108 = 23 + 69 + 13 + 3 * 100% = 23 + 69 + 13 + 3 = 108
4.43 plus 15 percent is 5.0945
8 plus 15 = 23
15% of 23 is 3.45
12 + 15 + 63 + 12 + 24 + 34 + 23 + 15 = 198
