1. The problem involves understanding the quantities of socks of different colors: red (90), pink (80), green (70), black (60), and blue (50). 2. We are given the counts directly, so no formula is needed to find these values. 3. To analyze or compare these quantities, we can consider their differences or ratios. 4. For example, the difference between red and blue socks is calculated as: $$90 - 50 = 40$$ 5. This means there are 40 more red socks than blue socks. 6. Similarly, the difference between pink and black socks is: $$80 - 60 = 20$$ 7. These comparisons help understand the distribution of sock colors. 8. If needed, we can also calculate the total number of socks: $$90 + 80 + 70 + 60 + 50 = 350$$ 9. This total represents all socks combined. 10. This problem is primarily about interpreting and comparing given data values.
