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

### Instruction:
Brianne saves $10 in January. Each month, she saves twice as much as her previous month's savings. How much will she save in May?

### Response:
Brianne saves $10 x 2 = $<<10*2=20>>20 in February.
She will save $20 x 2 = $<<20*2=40>>40 in March.
She will save $40 x 2 = $<<40*2=80>>80 in April.
Therefore, she will save $80 x 2 = $<<80*2=160>>160 in May.
#### 160
