1. **State the problem:** Calculate the percentage growth of net cash flow from Q2 to Q3 for Grand Slam Training Center. 2. **Formula used:** $$\text{Percentage Growth} = \left(\frac{\text{Net Cash Flow}_{Q3} - \text{Net Cash Flow}_{Q2}}{\text{Net Cash Flow}_{Q2}}\right) \times 100\%$$ 3. **Given values:** $$\text{Net Cash Flow}_{Q2} = -7500$$ $$\text{Net Cash Flow}_{Q3} = -800$$ 4. **Calculate the difference:** $$-800 - (-7500) = -800 + 7500 = 6700$$ 5. **Substitute into the formula:** $$\text{Percentage Growth} = \left(\frac{6700}{-7500}\right) \times 100\%$$ 6. **Simplify the fraction:** $$\text{Percentage Growth} = \left(\frac{\cancel{6700}}{\cancel{-7500}}\right) \times 100\% = -0.8933 \times 100\%$$ 7. **Calculate the final percentage:** $$-0.8933 \times 100\% = -89.33\%$$ 8. **Interpretation:** The net cash flow decreased by approximately 89.33% from Q2 to Q3.
