<human>:  Jefferson hires a carriage to go to the church. It is 20 miles away. The horse can go 10 miles per hour. It cost $30 per hour plus a flat fee of $20. How much did he pay for the carriage?
<bot>: How many hours did the carriage take? ** He paid for 20/10=<<20/10=2>>2 hours
How much did the carriage cost in total? ** That means the hourly fee was 30*2=$<<30*2=60>>60
How much did the carriage cost in total? ** So the total cost was 60+20=$<<60+20=80>>80
