### Instruction:
Jon's laundry machine can do 5 pounds of laundry at a time.  4 shirts weigh 1 pound and 2 pairs of pants weigh 1 pound.  If he needs to wash 20 shirts and 20 pants, how many loads of laundry does he have to do?

### Response:
 Anahitaji kufua paundi 20/4 = <<20/4=5>>5 za mashati
Anahitaji kufua paundi 20/2 = <<20/2=10>>10 za suruali
Hivyo, anahitaji kufua paundi 5+10 = <<5+10=15>>15 za nguo
Hivyo, anahitaji kufua mizigo 15/5 = <<15/5=3>>3.
