<human>:  Melissa sells a coupe for $30,000 and an SUV for twice as much. If her commission is 2%, how much money did she make from these sales?
<bot>: How much did the SUV cost? ** First find the total cost of the SUV: $30,000 * 2 = $<<30000*2=60000>>60,000
How much did the cars cost? ** Then add the cost of the coupe to find the total cost of the cars: $60,000 + $30,000 = $<<60000+30000=90000>>90,000
How much money did Melissa make from these sales? ** Multiplying that amount by Melissa's commission rate, we find her earnings are $90,000 * 2% = $<<90000*2*.01=1800>>1800
#### 1800
