A party store offers small balloons and large balloons. You can choose from pink, blue, green, and yellow balloons. You can choose from silver, gold, and white ribbons. Use the counting principle to find the number of different ways you can choose a balloon with a ribbon.
There are $2$ choices for balloon size, $4$ choices for balloon color, and $3$ choices for ribbon color, for a total of $2\cdot 4\cdot 3 = \boxed{24}$ different combinations.

To choose a balloon with a ribbon, you have $2$ options for the size, small or large. Once you have picked a size, you have $4$ color options for the balloon. Finally, you have $3$ options for the ribbon color. To find the total number of different ways to choose a balloon with a ribbon, you multiply the number of options for each step: $2$ choices for balloon size, times $4$ choices for balloon color, times $3$ choices for ribbon color, which equals $24$ possible combinations in total.
There are $2$ choices for balloon size, $4$ choices for balloon color, and $3$ choices for ribbon color, for a total of $2\cdot 4\cdot 3 = \boxed{24}$ different combinations.

You can choose small or large balloon ($2$ options), then one of $4$ color options for the balloon and one of $3$ options for the color of the ribbon. To find the total number of different ways to choose a balloon with a ribbon, you multiply the number of options for each step to get $2\cdot 4\cdot 3 = 24$ possible combinations.
