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

### Instruction:
A math teacher had $100 to buy three different types of calculators. A basic calculator costs $8. A scientific calculator costs twice the price as the basic while a graphing calculator costs thrice the price as the scientific. How much change did she receive after buying those three different types of calculators?

### Response:
 Kikokotoo cha msingi kina gharama ya $8 x 5 = $<<8*5=40>>40.
Kikokotoo cha kisayansi kina gharama ya $8 x 2 = $<<8*2=16>>16.
Kikokotoo cha grafu kina gharama ya $16 x 3 = $<<16*3=48>>48.
Hivyo, alitumia $8 + $16 + $48 = $<<8+16+48=72>>72 kwa kikokotoo zote tatu.
Hivyo, mwalimu wa hesabu alipokea $100 - $72 = $<<100-72=28>>28 kama pesa taslimu.
