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

### Instruction:
To earn money for her new computer, Tina sells handmade postcards. In a day, she can make 30 such postcards. For each postcard sold, Tina gets $5. How much money did Tina earn if she managed to sell all the postcards she made every day for 6 days?

### Response:
 Tina alitengeneza kadi za posta kwa siku 6, hivyo amefanya kadi za posta 6 siku * 30 kadi/siku = <<6*30=180>>180 kadi za posta.
Kwa kila kadi ya posta, Tina hupata $5, hivyo ikiwa aliuza kila kadi, alipata kadi za posta 180 * $5/kadi = $<<180*5=900>>900.
Tina alihitaji $900 kununua kompyuta mpya, hivyo alifanikiwa kununua moja baada ya yote.
