<PRE><B>Question 229417</B>
What number increased by 15% is 230


Step 1.  15% means 0.15.


Step 2.  Let n be the number


Step 3.  Let n+0.15n=230 since the number is increased by 15% to 230.


Step 4.  Then, 1.15n=230 and solve using the following steps.


Divide 1.15 to both sides of the equation

{{{cross(1.15)n/cross(1.15)=230/1.15}}}


{{{n=200}}}


Step 5.  ANSWER: The number is 200.


I hope the above steps were helpful.
