Q. Roxanne is ordering a new skateboard. There are

3

shapes to choose from and

5

types of wheels. How many different skateboards can Roxanne create?

\newline

\_\_\_\_

skateboards

Apply Basic Counting Principle: Apply the Basic Counting Principle. To find the total number of different skateboards Roxanne can create, we need to multiply the number of choices for each independent option. We have: $\newline$ Number of skateboard shape choices = $3$ $\newline$ Number of wheel type choices = $5$ $\newline$ Calculate the total number of different skateboards by multiplying the number of choices for shapes by the number of choices for wheels. $\newline$ $3 \times 5 = 15$
