 
 <translate> 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? Give me reasons, before answering the question <hau> Mai sayar da kayayyaki yana kara farashin abin da yake sayarwa da dala biyar duk lokacin da wani ya sayi shi. Mutane biyu sun shiga yakin neman sayen tebur kuma farashin ya tashi daga $15 zuwa $65 kafin a sayar da teburin. Sau nawa ne kowane mutum ya ba da tayin a kan teburin? Ka ba ni dalilai, kafin ka amsa tambaya
