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

### Instruction:
An auctioneer raises the price of an item he is auctioning by $5 every time someone new bids on it. Two people enter a bidding war on a desk and the price goes from $15 to $65 before the desk is sold. How many times did each person bid on the desk?

### Response:
 Bei ya meza ilipanda $65 - $15 = $<<65-15=50>>50.
Kwa $5 kwa zabuni, kulikuwa na zabuni 50 / 5 = <<50/5=10>>10 kwa meza.
Walikuwepo wazabuni wawili, hivyo kila mmoja alitoa zabuni mara 10 / 2 = <<10/2=5>>5 kwa meza.
