Below is an instruction that describes a task. Write a response that appropriately completes the request in Swahili. Please answer in Swahili.

### Instruction:
A town has ten neighborhoods, each having four roads passing through them. Each of the roads has 250 street lights on each opposite side. Calculate the total number of street lights on all the roads of the neighborhoods in the town.

### Response:
 Ikiwa kila barabara ina taa za mitaani 250 kila upande, kuna taa za mitaani 250*2 = <<250*2=500>>500 kwenye kila barabara.
Kwa kuwa kila mtaa una barabara nne zinazopita, idadi jumla ya taa za mitaani katika mtaa mmoja ni 500*4 = <<500*4=2000>>2000.
Mitaa kumi, kila mmoja na taa za mitaani 2000, ina jumla ya taa za mitaani 2000*10 = <<2000*10=20000>>20000.
