###Human: After collecting all the old electronics in their house, Lauryn made $2000 from selling the items on eBay. If her friend Aurelia also made 70% of what she sold on eBay after selling her used electronics, calculate the total amount of money the two friends made on eBay., ### Assistant: If Lauryn made $2000 from eBay, then her friend made 70/100*$2000 =$1400
In total, the two friends made $2000+$1400 = $3400 
 So the answer is :  3400
