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

### Instruction:
 Lengo la mazoezi ya Shawna ni kufanya situps 30. Jumatatu, Shawna alifanikiwa kufanya situps 12 tu, hivyo akaamua kufanya zaidi siku ya Jumanne. Hata hivyo, alifanikiwa kufanya situps 19 tu siku ya Jumanne. Shawna anapaswa kufanya situps ngapi siku ya Jumatano ili kufikia lengo lake la chini na kufidia zile ambazo hakufanya?



### Response:
 Jumatatu, Shawna alikosa situps 30 - 12 = <<30-12=18>>18
Jumanne, Shawna alikosa situps 30 - 19 = 11
Jumatano, Shawna anapaswa kufanya situps 30 + 18 + 11 = <<30+18+11=59>>59
