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

### Instruction:
Three companies, A, B, and C, each purchased 10 ad spaces on a newspaper, with each ad space having a size of 12 foot by 5-foot rectangle. If each square foot ad was charged at $60, how much money did the three pay for the ads combined?

### Response:
 Kwa kuwa futi moja ni sawa na inchi 12, basi mstatili wa futi 12 kwa 5 ni sawa na 12*12 * 5 = 600*5 = 3000 inchi mraba.
Kwa kuwa kila futi mraba ililipwa $60, basi $60*600 =$<<60*600=36000>>36000 ililipwa kwa mstatili wa futi 12 kwa 5.
Jumla ya gharama ya kampuni tatu kwa matangazo ni $36000 x 3 = $<<36000*3=108000>>108000.
