The accompanying sketch represents a maze of oneway streets in a city in the United States. The traffic volume through certain blocks during an hour has been measured. Suppose that the vehicles leaving the areaduring this hour were exactly the same as those entering it.
What can you say about the traffic volume at thefour locations indicated by a question mark? Can you figure out exactly how much traffic there was on each block? If not, describe one possible scenario. For eachof the four locations, find the highest and the lowest possible traffic volume.

A television program director must schedule comedy skits and musical numbers for prime-time variety shows. Each comedy skit requires 2 hours of rehearsal time, costs 3000, and brings in 20,000 from the shows sponsors. Each musical number requires 1 hour of rehearsal time, costs 6000, and generates 12,000. If 250 hours are available for rehearsal and 600,000 is budgeted for comedy and music, how many segments of each type should be produced to maximize income? Find the maximum income.arrow_forward
