CollegeABCDE
Demand (application received)3000600250012003300
Intake (available seats)15001800100027002200

The demand for college B is approximately what percent of the demand for college C?

The correct answer is
24%

Understanding the Demand Data

The question asks us to find the demand for college B as a percentage of the demand for college C. We need to use the data provided in the table, specifically the 'Demand (application received)' figures for colleges B and C.

From the table:

  • Demand for College B = 600 applications
  • Demand for College C = 2500 applications

Calculating Percentage Demand

To calculate what percentage the demand for college B is of the demand for college C, we use the formula:

Percentage = (Part / Whole) * 100

In this case:

  • Part = Demand for College B
  • Whole = Demand for College C

The calculation is as follows:

$$ \text{Percentage} = \frac{\text{Demand for College B}}{\text{Demand for College C}} \times 100 $$

Substituting the values:

$$ \text{Percentage} = \frac{600}{2500} \times 100 $$

Final Answer Derivation

Now, we simplify the fraction:

$$ \frac{600}{2500} = \frac{6}{25} $$

Multiply by 100 to get the percentage:

$$ \text{Percentage} = \frac{6}{25} \times 100 $$

$$ \text{Percentage} = 6 \times \frac{100}{25} $$

$$ \text{Percentage} = 6 \times 4 $$

$$ \text{Percentage} = 24\% $$

Therefore, the demand for college B is 24% of the demand for college C.
