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

### Instruction:
 Tyler ana $100. Ikiwa ananunua makasi 8 kwa $5 kila moja na mafutundo 10 kwa $4 kila moja, kiasi gani cha pesa chake kinabaki?


### Response:
 8 * $5 = $<<8*5=40>>40 ni bei ya makasi 8.
10 * $4 = $<<10*4=40>>40 ni bei ya mafutundo 10.
Unaweza kupata gharama jumla kwa kuongeza gharama ya makasi na mafutundo: $40 + $40 = $<<40+40=80>>80
$100 - $80 = $<<100-80=20>>20 ni kiasi kilichobaki cha pesa yake.
