To find the total number of beads Zoe needs to buy to make 8 pairs of earrings, we can break down the problem step by step.

1. **Identify the number of beads needed for one pair of earrings:**
   - Small blue beads: 3
   - Small metallic beads: 1
   - Large green beads: 2

2. **Calculate the total number of each type of bead needed for 8 pairs of earrings:**
   - For small blue beads:
     $$
     \text{Total small blue beads} = 3 \times 8
     $$
   - For small metallic beads:
     $$
     \text{Total small metallic beads} = 1 \times 8
     $$
   - For large green beads:
     $$
     \text{Total large green beads} = 2 \times 8
     $$

3. **Perform the calculations:**
   - Total small blue beads:
     $$
     3 \times 8 = 24
     $$
   - Total small metallic beads:
     $$
     1 \times 8 = 8
     $$
   - Total large green beads:
     $$
     2 \times 8 = 16
     $$

4. **Sum the total number of beads:**
   $$
   \text{Total beads} = \text{Total small blue beads} + \text{Total small metallic beads} + \text{Total large green beads}
   $$
   $$
   \text{Total beads} = 24 + 8 + 16
   $$

5. **Final calculation:**
   $$
   24 + 8 + 16 = 48
   $$

Therefore, Zoe will need to buy a total of **48 beads** to make 8 pairs of earrings.
Zoe needs to buy a total of 48 beads to make 8 pairs of earrings.
