Each pole on a road intersection has 4 street lights. If the number of poles at each intersection is 6, and the road has 4 intersections, calculate the total number of functioning street lights if 20 streetlights from the total number are not working.
If the number of poles at each intersection is 6, and the road has 4 intersections, the total number of poles having street lights is 6*4=<<6*4=24>>24
Since each pole on a road intersection has 4 street lights, the total number of streetlights in all the poles is 24*4=<<24*4=96>>96
If 20 streetlights from the total number are not working, the number of functioning street lights is 96-20=<<96-20=76>>76
