Explanation:

⚡ Using what you learned: Organizing Data in Tables · converting between fractions, decimals, percents

Step 1: Find the total number of square counters

Identify the column for "Square" counters and sum the values:

$$ 13 \text{ (Red)} + 7 \text{ (Blue)} = 20 \text{ square counters} $$

Step 2: Identify the number of blue square counters

From the "Square" column, locate the row for "Blue":

$$ 7 \text{ blue square counters} $$

Step 3: Calculate the percentage

Divide the number of blue square counters by the total number of square counters and multiply by 100:

$$ \frac{7}{20} \times 100 = 35\% $$

Answer:

35%
