"""Generate Python code that can solve the question in Example 4. All questions are based on the GSM8K dataset. 

[Example 1]

Question: Janet’s ducks lay 16 eggs per day. She eats three for breakfast every morning and bakes muffins for her friends every day with four. She sells the remainder at the farmers' market daily for $2 per fresh duck egg. How much in dollars does she make every day at the farmers' market?

Output:

```python

daily_eggs_laid = 16

eggs_for_breakfast = 3

eggs_for_muffins = 4

eggs_for_sale = daily_eggs_laid - eggs_for_breakfast - eggs_for_muffins

price_per_egg = 2

ans = eggs_for_sale * price_per_egg

```

[Example 2]

Question: A robe takes 2 bolts of blue fiber and half that much white fiber. How many bolts in total does it take?

Output:

```python

blue_fiber_bolts = 2

white_fiber_bolts = blue_fiber_bolts / 2

ans = blue_fiber_bolts + white_fiber_bolts

```

[Example 3]

Question: Betty is saving money for a new wallet which costs $100. Betty has only half of the money she needs. Her parents decided to give her $15 for that purpose, and her grandparents twice as much as her parents. How much more money does Betty need to buy the wallet?

Output:

```python

wallet_cost = 100

betty_savings_initial = wallet_cost / 2

parents_contribution = 15

grandparents_contribution = parents_contribution * 2

total_savings = betty_savings_initial + parents_contribution + grandparents_contribution

ans = wallet_cost - total_savings

```
