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

### Instruction:
Roberta takes $158 with her on a shopping trip to the mall. She spends $45 on new shoes, $17 less on a new bag, and a quarter of the price of the bag for lunch. How much money does she have left after these purchases?

### Response:
Roberta spend $45 - $17 = $<<45-17=28>>28 on a new bag.
Roberta spend 1/4 * $28 = $<<1/4*28=7>>7 on lunch.
Roberta spend $45 + $28 + $7 = $<<45+28+7=80>>80 in total.
Roberta has $158 - $80 = $<<158-80=78>>78 left.
