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

### Instruction:
Marjorie works as a baker. Every day, she makes twice as many cakes as she did the day before. On the sixth day, she makes 320 cakes. How many cakes did Marjorie make on the first day?

### Response:
 Siku ya tano, Marjorie alitengeneza keki 320 / 2 = <<320/2=160>>160.
Hivyo, siku ya nne, alitengeneza keki 160 / 2 = <<160/2=80>>80.
Siku ya tatu, alitengeneza keki 80 / 2 = <<80/2=40>>40.
Siku ya pili, alitengeneza keki 40 / 2 = <<40/2=20>>20.
Siku ya kwanza, alitengeneza keki 20 / 2 = <<20/2=10>>10.
