Emily purchased lemons for $600. She sold 3/4 of these at a loss of 20% and the remaining at a gain of 20%. How much percent does she gain or lose in the whole transaction?

  $  600 x 3/4 = 450  at a loss 0f 20%  so she received;   450 x .8 = $ 360

 

       600-450 = $ 150 lemons left   

 

  $  150  x 1.20   = $ 180

 

180 + 360 = 540     she lost  60$ overall     60/600 = 10%
