1. **State the problem:** Sue wants to make 60 gingerbread men. The recipe quantities given are for 20 gingerbread men. We need to find how much of each ingredient is required for 60 gingerbread men and then determine how much more Sue needs compared to what she already has. 2. **Calculate the required amount for 60 gingerbread men:** Since the recipe is for 20 gingerbread men, multiply each ingredient by $\frac{60}{20} = 3$. - Flour: $350 \times 3 = 1050$ g - Ground ginger: $10 \times 3 = 30$ g - Butter: $100 \times 3 = 300$ g - Brown sugar: $175 \times 3 = 525$ g - Syrup: $60 \times 3 = 180$ g - Eggs: $1 \times 3 = 3$ eggs 3. **Compare with what Sue has and find how much more she needs:** - Flour: Needs $1050$ g, has $1000$ g (1 kg) $$1050 - 1000 = 50 \text{ g more}$$ - Ground ginger: Needs $30$ g, has $200$ g $$200 - 30 = 170 \text{ g extra (no need to buy)}$$ - Butter: Needs $300$ g, has $500$ g $$500 - 300 = 200 \text{ g extra (no need to buy)}$$ - Brown sugar: Needs $525$ g, has $600$ g $$600 - 525 = 75 \text{ g extra (no need to buy)}$$ - Syrup: Needs $180$ g, has $100$ g $$180 - 100 = 80 \text{ g more}$$ - Eggs: Needs $3$, has $2$ $$3 - 2 = 1 \text{ egg more}$$ 4. **Final answer:** Sue needs to buy: - 50 g more flour - 80 g more syrup - 1 more egg She has enough ground ginger, butter, and brown sugar.
