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

### Instruction:
At the end of the first quarter, the winning team had double the points of the losing team. At the end of the second quarter, the winning team had 10 more points than it started with. At the end of the third quarter, the winning team had 20 more points than the number it had in the second quarter. If the total points the winning team scored in the game was 80, and the losing team had 10 points in the first quarter, calculate the total number of points the team scored in the fourth quarter.

### Response:
 Kwa kuwa timu ya kushinda ilikuwa na mara mbili ya alama za timu ya kushindwa mwishoni mwa robo ya kwanza, na timu ya kushindwa ilikuwa na alama 10, timu ya kushinda ilikuwa na 2*10=<<10*2=20>>20 alama.
Mwishoni mwa robo ya pili, timu ya kushinda ilikuwa na alama 10 zaidi kuliko ilianza nazo, jumla ya alama 10+20=30.
Ikiwa jumla ya alama ambazo timu ya kushinda ilipata katika mchezo huo ilikuwa 80, ilipata alama 80-30=<<80-30=50>>50 katika robo ya pili na ya tatu.
Mwishoni mwa robo ya tatu, timu ya kushinda ilikuwa na alama 20 zaidi ya idadi iliyokuwa nayo katika robo ya pili, jumla ya alama 30+20=<<30+20=50>>50.
Timu ilipata alama 50 katika robo ya tatu, maana yake ilipata alama 80-50=<<80-50=30>>30 katika robo ya nne.
