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

### Instruction:
Jesse received $50 as a gift to buy what she wants. She goes to the mall and falls in love with a novel that costs her $7. Then she went to lunch because she was very hungry and spent twice as much as the novel cost her. How much money did Jesse have left after going to the mall?

### Response:
 Jesse alinunua riwaya kwa $<<7=7>>7.
Jesse alikula chakula cha mchana na kutumia mara mbili ya gharama ya riwaya, $7 x 2 = $<<7*2=14>>14.
Baada ya kula na kununua, Jesse alikuwa na $50 - $14 -$7 = $<<50-14-7=29>>29 zilizobaki.
