Question: 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? Is final answer 15?
Answer: When she picks 1/4 of the number of tomatoes, she goes home with 1/4*100 = <<1/4*100=25>>25 tomatoes.
The total number of tomatoes remaining will be 100-25 = <<100-25=75>>75 tomatoes.
After picking 20 more tomatoes the following week, the number of tomatoes remaining is 75-20 = <<75-20=55>>55 tomatoes.
The next week she picks twice the number she picked the previous week, that is 20*2 = <<20*2=40>>40 tomatoes.
The total number of tomatoes remaining after the final picking is 55-40 = <<55-40=15>>15 tomatoes.
