Solution Steps

To find the approximate cost for 2013-2014, we need to calculate the increase in cost based on the given percentage and then add that increase to the original cost from 1993-1994.

  1. Calculate the increase in cost by multiplying the original cost by the percentage increase (240%).
  2. Add the increase to the original cost to get the new cost.
  3. Round down to the nearest dollar.
Step 1: Calculate the Increase in Cost

The original cost in 1993-1994 was \( \$2331 \). The percentage increase over twenty years was \( 240\% \).

To find the increase in cost: \[ \text{Increase} = 2331 \times \frac{240}{100} = 2331 \times 2.4 = 5594.4 \]

Step 2: Calculate the New Cost

Add the increase to the original cost to get the new cost: \[ \text{New Cost} = 2331 + 5594.4 = 7925.4 \]

Step 3: Round Down to the Nearest Dollar

Round down the new cost to the nearest dollar: \[ \text{Approximate Cost} = \lfloor 7925.4 \rfloor = 7925 \]

Final Answer

The approximate cost for 2013-2014 was \( \boxed{7925} \).
