Two traffic signal systems are being considered for an intersection. One system costs $34,000 formstalla on and as an eficiency rating of 76% requires 26 k power (output), incurs a user cost of $0.26 per vehicle, and has a life of 9 years. A second system costs $46,000 to install, has an efficiency rating of 92% requires 37 kW power (output), has a user cost of S0.24 per vehicle, and has a life of 18 years. Annual maintenance costs are $80 and $95, respectively. MARRs 12% per year. How many vehicles must use the intersection to ustify the second system f en electricity costs S O k h? Assume salvage ue for each system equals zero. Project the difference in the user cost as savings for the second system. There are approximately 8,760 hours/year.

(Round up to the nearest whole number.)
