We know that 100% of a number, is the number itself. In our case 100% of 150 is 150. To find a 28% increase of a number we can follow this route.
Lets create a ratio to find how much is this 128%. Lets call it X since is unknown.
If 100% is 150.
Then 128% is X
Lets cross multiply, 100 times x equal to 128 times 150.
100x=150*128
100x=19200
Divide both sides with 100.
100x/100 = 19200/100
x=192 is 128% of 150.
To find out with how much is increased we can do this: 192-150= 42
