1. **State the problem:** We are given the number of bins in each toy count range and need to find the total number of bins. 2. **Data given:** Number of bins for each toy range: - 1-10 toys: 1 bin - 11-20 toys: 9 bins - 21-30 toys: 7 bins - 31-40 toys: 3 bins - 41-50 toys: 5 bins - 51-60 toys: 6 bins - 61-70 toys: 10 bins - 71-80 toys: 1 bin 3. **Formula used:** Total bins = sum of bins in all categories 4. **Calculate the total:** $$\text{Total bins} = 1 + 9 + 7 + 3 + 5 + 6 + 10 + 1$$ 5. **Perform the addition:** $$1 + 9 = 10$$ $$10 + 7 = 17$$ $$17 + 3 = 20$$ $$20 + 5 = 25$$ $$25 + 6 = 31$$ $$31 + 10 = 41$$ $$41 + 1 = 42$$ 6. **Final answer:** There are **42 bins** in total.
