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

### Instruction:
 Eva learns for two semesters in a year. In 2019, she scored ten more marks in maths in the first semester than the second, 15 marks less in arts, and 1/3 marks less in science in the first semester than the second. If she got 80 marks in maths in the second semester, 90 marks in arts, and 90 in science, what's the total number of her marks in all the semesters?


### Response:
 Eva alipata alama 80+10 = <<80+10=90>>90 katika hesabu katika semester ya kwanza.
Alipata alama 90-15 = <<90-15=75>>75 katika sanaa katika semester ya kwanza.
Alipata alama 1/3 chini katika sayansi katika semester ya kwanza kuliko ya pili, ambayo ni 1/3*90 = <<1/3*90=30>>30
Alama yake katika sayansi katika semester ya kwanza ni 90-30 = <<60=60>>60
Jumla ya alama alizopata katika semester ya kwanza ni 90+75+60 = <<90+75+60=225>>225
Jumla ya alama alizopata katika semester ya pili ni 90+90+80 = <<90+90+80=260>>260
Jumla ya alama zake katika semesters zote ni 260+225 = <<260+225=485>>485
