To calculate the total number of tubes of paint the teacher bought, you need to multiply the number of packs by the number of tubes in each pack. The appropriate equations would be:
1. **18 + 18 + 18 + 18 = 72** (This shows the total by adding each pack's tubes individually.)
2. **4 × 18 = 72** (This correctly uses multiplication to represent the total number of tubes.)
So, the two correct equations that represent the total number of tubes of paint the teacher bought are:
- **18 + 18 + 18 + 18 = 72**
- **4 × 18 = 72**
