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?
+4711 3/4 of $600 = $450
(1-0.2=0.8)
80% of $450 = $360 (the lemons she sold at a loss)
1/4 of 600 = 150
(1+0.2=1.2)
120% of 150=$180 (the lemons she sold at a gain)
180+360=540
540/600= 90%
100-90= 10%
She lost 10% in the whole transaction.
I hope this is right or this will be awkward :)
