### Instruction:
A plumber bought 10 meters of copper and 5 more meters of plastic pipe. If each meter cost $4, how much did the plumber spent on the copper and plastic pipe?

### Response:
 Alinunua mita 10 + 5 = <<10+5=15>>15 za mabomba ya plastiki.
Jumla ya mita za shaba na mabomba ya plastiki ni 15 + 10 = <<15+10=25>>25.
Fundi bomba alitumia $4 x 25 = $<<4*25=100>>100 kwenye shaba na mabomba ya plastiki.
