Andy, Bob and Chuck run a gardening business. Andy pays all the annual fixed costs (insurance, telephone line rental, etc.) by installments, which amount to $400 per week. Bob buys the materials for any job they do. Chuck collects the payment for jobs. They split all profits evenly and settle down after every job is completed. They have just done a landscaping and re-fencing job for Mrs. Smith that took the three of them exactly two weeks. Materials cost $1,400 and Mrs. Smith paid Chuck $4,900. How much does Chuck owe Andy and Bob?
