How many branches would a tree diagram have to represent the possible combinations of ice cream?

An ice cream shop has 15 flavors with 6 different toppings.

90 branches

Step-by-step explanation:

Since there are only 2 variables that might change the outcomes, we can simply multiply those variables by each other to get the number of outcomes.

15 * 6 = 90

To be more in depth with this ...

For each flavor there would be 6 topping options, right?

So if there are 15 flavors, we would have 90 different combinations of ice cream.

There isn't a varying cone flavor or something else to change the outcome, which is why the tree diagram would stop after the topping part.
