1. **State the problem:** We know that 39,700 copies sold represent 9.4% of the total copies sold to date. We need to find the total number of copies sold, denoted as $T$. 2. **Write the equation:** The problem states: $$39700 = 9.4\% \times T$$ which can be rewritten as $$39700 = 0.094 \times T$$ 3. **Solve for $T$:** To isolate $T$, divide both sides by 0.094: $$T = \frac{39700}{0.094}$$ 4. **Show intermediate step with cancellation:** $$T = \frac{\cancel{39700}}{\cancel{0.094}}$$ (This is just symbolic cancellation to indicate division, actual numbers remain.) 5. **Calculate the value:** $$T = 422340.4255...$$ 6. **Round to the nearest whole number:** $$T \approx 422340$$ **Final answer:** The total number of copies sold to date is approximately **422,340** copies.
