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

### Instruction:
When Suzy the librarian sat at her desk on Wednesday morning, she had 98 books ready for checkout. The same day, 43 books were checked out. The following day, 23 books were returned, but 5 books were checked out. On Friday, 7 books were returned. How many books did Suzy have?

### Response:
 Vitabu 43 vilipokodishwa Jumatano, Suzy alibaki na vitabu 98 – 43 = <<98-43=55>>55
Baada ya kurudishwa kwa vitabu 23 Alhamisi, alimaliza na vitabu 55 + 23 = <<55+23=78>>78
Hata hivyo, vitabu 5 vilikodishwa siku hiyo hiyo, maana yake vitabu 73 vilisalia.
Baada ya kurudishwa kwa vitabu 7 Ijumaa, Suzy alikuwa na vitabu 73 + 7 = <<73+7=80>>80
