pick the model that represents the problem.
two bar models: first blue with 0 at left, ? at 50%, 10 at 100%; second yellow with 0 at left, 10 at 50%, ? at 100%
how many pairs of shoes does meredith have in all?

Explanation:

Step1: Define the unknown total

Let $x$ = total pairs of shoes.

Step2: Set up percentage equation

50% of $x$ equals 10, so:
$$0.5x = 10$$

Step3: Solve for total shoes

Divide both sides by 0.5:
$$x = \frac{10}{0.5}$$

Answer:

20
The correct model is the yellow bar (bottom one), where 50% corresponds to 10, and 100% (the total) is the unknown value.
