Let me work through this problem step by step.
What we have in the kitchen:
- 1250g of flour
- 1825g caster sugar
- 855g brown sugar
- 760g butter
Gingerbread Cookies recipe (in kg):
- 0.145kg butter = 145g
- 0.9kg brown sugar = 900g
- 1.38kg flour = 1380g
Checking:
- Butter: Need 145g, have 760g → Have enough ✓
- Brown sugar: Need 900g, have 855g → NOT enough, need 900 - 855 = 45g more
- Flour: Need 1380g, have 1250g → NOT enough, need 1380 - 1250 = 130g more
Custard Creams recipe (in kg):
- 0.85kg butter = 850g
- 0.4kg caster sugar = 400g
- 1.4kg flour = 1400g
Checking:
- Butter: Need 850g, have 760g → NOT enough, need 850 - 760 = 90g more
- Caster sugar: Need 400g, have 1825g → Have enough ✓
- Flour: Need 1400g, have 1250g → NOT enough, need 1400 - 1250 = 150g more
Brownies recipe (in kg):
- 1.2kg butter = 1200g
- 0.44kg brown sugar = 440g
- 0.9kg caster sugar = 900g
- 0.85kg flour = 850g
Checking:
- Butter: Need 1200g, have 760g → NOT enough, need 1200 - 760 = 440g more
- Brown sugar: Need 440g, have 855g → Have enough ✓
- Caster sugar: Need 900g, have 1825g → Have enough ✓
- Flour: Need 850g, have 1250g → Have enough ✓
Let me verify my calculations:
Gingerbread Cookies:
- 0.145 × 1000 = 145g butter. Have 760g. 760 > 145 ✓
- 0.9 × 1000 = 900g brown sugar. Have 855g. 855 < 900. Need 45g more.
- 1.38 × 1000 = 1380g flour. Have 1250g. 1250 < 1380. Need 130g more.
Custard Creams:
- 0.85 × 1000 = 850g butter. Have 760g. 760 < 850. Need 90g more.
- 0.4 × 1000 = 400g caster sugar. Have 1825g. 1825 > 400 ✓
- 1.4 × 1000 = 1400g flour. Have 1250g. 1250 < 1400. Need 150g more.
Brownies:
- 1.2 × 1000 = 1200g butter. Have 760g. 760 < 1200. Need 440g more.
- 0.44 × 1000 = 440g brown sugar. Have 855g. 855 > 440 ✓
- 0.9 × 1000 = 900g caster sugar. Have 1825g. 1825 > 900 ✓
- 0.85 × 1000 = 850g flour. Have 1250g. 1250 > 850 ✓
