<human>:  Jenna works as a truck driver. She gets paid $0.40 cents per mile. If she drives 400 miles one way, how much does she get paid for a round trip?
<bot>: How many miles does Jenna drive? ** First find the total number of miles Jenna drives: 400 miles/way * 2 ways = 800 miles
How much does Jenna get paid? ** Then multiply that number by her pay per mile to find her total pay: 800 miles * $0.40/mile = $<<800*0.4=320>>320
#### 320
