To find the total number of possible salad combinations Bella can order, we can use the fundamental principle of counting. Bella can choose:
- 1 green from 3 options,
- 1 meat from 4 options,
- 1 dressing from 5 options.
The total number of combinations can be calculated by multiplying the number of choices for each category together:
\[ \text{Total combinations} = (\text{Number of greens}) \times (\text{Number of meats}) \times (\text{Number of dressings}) \]
Substituting the values:
\[ \text{Total combinations} = 3 \times 4 \times 5 = 60 \]
Therefore, Bella can order 60 different salad combinations.
