Below is an instruction that describes a task. Write a response that appropriately completes the request in English. Please answer in English.

### Instruction:
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.

### Response:
If Lauryn made $2000 from selling her used electronics on eBay, then her friend made 70/100*$2000 =$<<70/100*2000=1400>>1400
In total, the two friends made $2000+$1400 = $<<2000+1400=3400>>3400 from selling their used electronics on eBay.
#### 3400
