Math
would you really have to multiply .08 and .12 by 100 or could you leave it the way it is?
March 25, 2010

Math
All you have to do is multiply parts of the 2500 by .08 and .12 then find which amount is the same. EXP 1250 * .08 = 100 1250 * .12 = 150 since those don't match go to 1300*.08 and 1200*.12 and so on untill you find the same answer
