### Instruction:
 Duka la keki linatoza $5 kwa kipande cha keki. Wanakata kila keki nzima katika vipande 4. Duka la keki litapata kiasi gani ikiuza keki 9?


### Response:
 Keki ni $5 x 4 = $<<5*4=20>>20 kwa sababu kuna vipande 4 kwa kila keki.
Duka la keki linapata $20 x 9 = $<<20*9=180>>180 ikiuza keki 9.
