In order to increase a number by 15% ,
multiply it by 1.15 .
37 x 1.15 = 42.55 .
Where does the 1.15 come from ?
The ' 1 ' is the entire number that you started with,
and the " .15 " is the additional 15% of it.
Increase number by 15% 15/100=0.15
Simply multiply by 1.15
So 37×1.15
The answer would be 42.55
Hope i helped
