Below is an instruction that describes a task. Write a response that appropriately completes the request in Swahili. Please answer in Swahili.

### Instruction:
A small pizza has 6 slices, a medium pizza has 8 slices whereas a large pizza has 12 slices. How many slices of pizza will you have if you bought a total of 15 pizzas and you know you ordered 4 small pizzas and 5 medium pizzas?

### Response:
 Tunajua uliagiza pizza 4 + pizza 5 = <<4+5=9>>9 pizza ndogo na za kati
Kwa kuwa jumla ya pizza ziliagizwa ni 15 basi 15-9 = <<15-9=6>>6 pizza kubwa ziliagizwa
Ikiwa pizza 1 ndogo ina vipande 6 basi pizza 4 ndogo zitakuwa na vipande 4*6 = <<4*6=24>>24
Vivyo hivyo, Ikiwa pizza 1 ya kati ina vipande 8 basi pizza 5 za kati zitakuwa na vipande 5*8 = <<8*5=40>>40
Vivyo hivyo, Ikiwa pizza 1 kubwa ina vipande 12 basi pizza 6 kubwa zitakuwa na vipande 6*12= 72
Jumla ya vipande vya pizza ndogo, kati na kubwa ni 24+40+72 = <<24+40+72=136>>136 vipande vya pizza
