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

### Instruction:
A tomato plant has 100 tomatoes. Jane picks 1/4 of that number for use in their house. After a week, she goes back and picks 20 more tomatoes, and the following week picks twice that number. What's the total number of fruits remaining on the tomato plant?

### Response:
 Wakati anachuma 1/4 ya idadi ya nyanya, anaenda nyumbani na 1/4 * 100 = <<1/4*100=25>>25 nyanya.
Idadi jumla ya nyanya zilizobaki baada ya kuchuma ya kwanza ni 100 - 25 = <<100-25=75>>75 nyanya.
Baada ya kuchuma nyanya 20 zaidi wiki inayofuata, idadi ya nyanya zilizobaki ni 75 - 20 = <<75-20=55>>55 nyanya.
Wiki inayofuata anachuma mara mbili ya idadi aliyoichuma wiki iliyopita, yaani 20 * 2 = <<20*2=40>>40 nyanya.
Idadi jumla ya nyanya zilizobaki baada ya kuchuma mwisho ni 55 - 40 = <<55-40=15>>15 nyanya.
