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

### Instruction:
One ticket to the underground costs $3. In one minute, the metro sells an average of 5 such tickets. What will be the earnings from the tickets in 6 minutes?

### Response:
 Katika dakika moja, mauzo ya tiketi yanapata 5 * 3 = $<<5*3=15>>15.
Hivyo katika dakika 6 tiketi zitawaletea metro 15 * 6 = $<<15*6=90>>90.
