An ice cream van sells 3 different ice-cream flavours with 4 different toppings.

How many different choices can be made using only one of the ice-cream flavours and only one of the toppings?

3 choices of ice cream times 4 toppings 12 choices

** v c s

n| x x x
f| x x x
m| x x x
p| x x x

v = vanilla
c = choc
etc
n = nuts
f = fudge
m = marshmallow

sure enough, 12 x marks :)

To solve this problem, we can multiply the number of choices for the ice-cream flavor by the number of choices for the toppings.

Given:
- 3 different ice-cream flavors
- 4 different toppings

First, let's calculate the number of choices for the ice-cream flavor:
- Since we can only choose one flavor, there are 3 different flavors to choose from.

Next, let's calculate the number of choices for the toppings:
- Similarly, since we can only choose one topping, there are 4 different toppings to choose from.

Now, let's multiply the number of choices for the ice-cream flavor by the number of choices for the toppings:
3 (choices for ice-cream flavor) * 4 (choices for toppings) = 12

Therefore, there are 12 different choices that can be made using only one of the ice-cream flavors and only one of the toppings.

To find the number of different choices that can be made using only one ice-cream flavor and one topping, we need to multiply the number of ice-cream flavors by the number of toppings.

Given that there are 3 different ice-cream flavors and 4 different toppings, we can multiply these two numbers together:

3 (ice-cream flavors) x 4 (toppings) = 12

Therefore, there are 12 different choices that can be made using only one ice-cream flavor and one topping.
