<human>:  The caretaker of the docks needs to buy some new line. He wants 3 feet of line for every foot of dock. Right now, there is 200 feet of dock, and he has 6 feet of new line. How many feet of line does he need to buy in total?
<bot>: How many feet of line does the caretaker need in total? ** 200*3 = <<200*3=600>>600 feet of line.
How many more feet of line does the caretaker need to buy? ** The caretaker needs to buy 600-6 = <<600-6=594>>594 feet of line.
