There was a $23.21\%$ increase in floor space.

Work Step by Step

RECALL: $\text{percent increase}=\dfrac{\text{increase in value}}{\text{original value}}$ The given problem has: original value =$28,000$ square feet increase in value = $6,500$ square feet Solve for the percent increase using the formula above to obtain: percent increase $= \dfrac{6,500}{28,000} \\=0.2321428571 \\=0.2321428571 \times 100\% \\=23.21428571\% \\\approx 23.21\%$ Thus, there was a $23.21\%$ increase in floor space.
