Two routes connect an origin-destination pair with performance functions t1 = 6 + 4x1 and t2 = 2 + 0.5x2 2 (with t's in minutes and x's in thousands of vehicles per hour). The origin-destination demand is 4000 veh/h at a travel time of 2 minutes, but for each additional minute beyond these 2 minutes, 100 fewer vehicles depart. Determine user equilibrium route flows and total vehicle travel time.

Two variables, num_boys and num_girls, hold the number of boys and girls that have registered for an elementary school. The variable budget holds the number of dollars that have been allocated to the school for the school year. Write code that prints out the per-student budget (dollar spent per student). If a division by zero error takes place, just print out the word "unavailable".
