If a man sells a bike at $9230, he incurs a 10% loss. How much
must he sell the bike to earn a 20% profit?
remembered I used 90% -> 9230
100% -> x
120% -> 120/100 x X
Not sure whether I should used 100% or 90% as $9230. But I
considered the fact that the 10% is the sum of the ORIGINAl amount
so, yea, the 9230 dollars should be 90%. Am I right or am I wrong?
Thank you! ;DDD
