1. The problem states that 80% of the days in April were sunny. We need to find how many days were sunny. 2. April has 30 days in total. 3. To find the number of sunny days, we use the formula: $$\text{Sunny days} = \text{Total days} \times \text{Percentage sunny}$$ 4. Substitute the values: $$\text{Sunny days} = 30 \times 0.80$$ 5. Calculate the multiplication: $$\text{Sunny days} = 24$$ 6. Therefore, there were 24 sunny days in April.
