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%
