### Instruction:
 Shule ilinunua masanduku 20 ya penseli mwanzoni mwa shule. Penseli zinapatikana katika masanduku ya masanduku 10 na kila sanduku lina gharama ya $2. Shule pia ilinunua masanduku 10 ya alama. Sanduku moja lina sanduku 5 na gharama ya $4. Shule ilitumia kiasi gani jumla?


### Response:
 Masanduku 20 ya penseli ni sawa na masanduku 20 x 10 = <<20*10=200>>200.
Penseli ziligharimu 200 x $2 = $<<200*2=400>>400.
Masanduku 10 ya alama ni sawa na masanduku 10 x 5 = <<10*5=50>>50.
Alama ziligharimu 50 x $4 = $<<50*4=200>>200.
Hivyo, shule ilitumia jumla ya $400 + $200 = $<<400+200=600>>600.
