To determine how many combinations the costumer can create if he only chooses one base, one topping and one sauce we need to apply the following:
[tex]\begin{gathered} \text{total}=\text{bases}\cdot\text{sauces}\cdot\text{toppings} \\ \text{total}=3\cdot4\cdot8=96 \end{gathered}[/tex]There can be a total of 96 stir-fry's.
