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

### Instruction:
Léa bought one book for $16, three binders for $2 and six notebooks for $1. Calculate the total cost of her purchases.

### Response:
 Léa ametumia 3 * $2 = $<<3*2=6>>6 kwa vijiti.
Ametumia 6 * $1 = $<<6*1=6>>6 kwa daftari.
Hivyo, jumla ya gharama ya manunuzi yake ni $16 + $6 + $6 = $<<16+6+6=28>>28
