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

### Instruction:
Louise is in a toy store. She already has 28 toys worth $10 each in her cart. On her way to the till she adds 20 teddy bears to the cart. If the $580 in Louise’s wallet is exactly enough to pay for all the toys, how much does each teddy bear cost?

### Response:
 Kwa kuanzia, gari la Louise lina vitu vyenye thamani ya $10 * 28 = <<10*28=280>>280
Ikiwa Louise analipia vitu vilivyokuwepo awali kwenye gari lake, mkoba wake utabaki na 580 - 280 = <<580-280=300>>300 dola.
Kugawanya kiasi kilichobaki kwa idadi ya dubu kunatoa 300/20 = <<300/20=15>>15 dola.
