A toll road commission is planning to locate garages for tow trucks along a 64mile circular highway. Each garage has a fixed cost of $1,500 per day. Towing jobs are equally likely along any point of the highway, and cost per mile towed is $32. If there were 1,500 towingjobs per day, what number of garages would minimize the sum of the fixed costs and towing costs? Instructions: Enter your answer as a whole number. garages
