Tom also hires an assistant who is paid $10.00 per hour for the time of the party (and nothing during the traveling or set-up or take-down time).

A certain customer requires that classical music be played at his party. Tom estimates that it would take an additional four hours to research this type of music and compile a playing list. Tom also feels that this request will not be repeated soon enough for the cost to be spread over any other customers, so the customer needs to be charged the full cost for the research time. Calculate the charge to this customer who lives 10 miles from the city center and gives a party for eight hours. (a) $415 (b) $460 (c) $485 (d) $480
