1. The problem is to convert temperatures from Celsius (°C) to Fahrenheit (°F) using the formula:
$$\text{°F} = 32 + 1.8 \times \text{°C}$$
2. For Recipe 1, convert 200 °C to °F:
$$\text{°F} = 32 + 1.8 \times 200$$
$$= 32 + 360$$
$$= 392$$
3. For Recipe 2, convert 185 °C to °F:
$$\text{°F} = 32 + 1.8 \times 185$$
$$= 32 + 333$$
$$= 365$$
4. For Recipe 3, convert 220 °C and 180 °C to °F:
First temperature:
$$\text{°F} = 32 + 1.8 \times 220$$
$$= 32 + 396$$
$$= 428$$
Second temperature:
$$\text{°F} = 32 + 1.8 \times 180$$
$$= 32 + 324$$
$$= 356$$
Final answers:
Recipe 1: 392 °F
Recipe 2: 365 °F
Recipe 3: 428 °F for 1 hour, then reduces to 356 °F for the final 20 minutes.
