The class enrollment increased by 3 students. This is the equivalent of 20%.
x + 12. If the unknown number is represented by x, the expression for a number increased by 12 would be x + 12.

6(n+12) + 3(n+6) = 58.5 6n + 72 + 3n + 18 = 58.5 9n + 90 = 58.5 9n = 58.5 - 90 9n = -31.5 n = -3.5
11 increased by 12 is the same as 11 plus 12 so the answer is 23
28.5 increased by 12 is 40.5. 28.5 increased by 12% of itself is 31.92.
The class enrollment increased by 3 students. This is the equivalent of 20%.
x + 12. If the unknown number is represented by x, the expression for a number increased by 12 would be x + 12.
35 increased by 12 percent is: an increase of 4.2 for a total of 39.2

800 + 12 = 812
-12+28 = 16
Any and every number can be increased by 3.
6(n+12) + 3(n+6) = 58.5 6n + 72 + 3n + 18 = 58.5 9n + 90 = 58.5 9n = 58.5 - 90 9n = -31.5 n = -3.5
12, 10 and 15 the are alternatively increased by 2 and 3
12 + 63% = 19.56
15 + 12% = 16.8
