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

### Instruction:
Every time she goes to the store, Felicity gets a lollipop. After she finishes them, she uses the sticks to build a fort. The fort needs 400 sticks to finish it. Her family goes to the store three times a week and she always goes. If the fort is 60% complete, how many weeks has Felicity been collecting lollipops for?

### Response:
The fort is 80 lollipops sticks because 400 x .6 = <<400*.6=240>>240
She has been going to the store for 80 weeks because 240 / 3 = <<240/3=80>>80
#### 80
