### Instruction:
 Morgan anaenda kwenye dirisha la kupata chakula na anaweka oda yake. Anapata hamburgeri kwa $4, vitumbua vya vitunguu kwa $2 na juisi laini kwa $3. Ikiwa analipa kwa noti ya $20, atapata kiasi gani cha pesa taslimu?


### Response:
 Jumla ya gharama ya chakula chake ni 4 + 2 + 3 = <<4+2+3=9>>9 dola.
Pesa taslimu anayopata ni 20 - 9 = <<20-9=11>>11 dola.
