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

### Instruction:
Emily went to the store and bought art supplies for $20 and 2 skirts that cost the same amount of money. She spent a total of $50. How much did Emily pay for each of the skirts?

### Response:
 Kwanza, toa gharama ya vifaa vya sanaa kutoka kwenye jumla ya kiasi alichotumia ili kupata kiasi ambacho Emily alilipa kwa sketi: $50 - $20 = $<<50-20=30>>30
Kisha ugawe kiasi hicho kwa idadi ya sketi ili kupata gharama ya kila sketi: $30 / 2 = $<<30/2=15>>15
