1. The problem asks us to evaluate the expression $$9000(1 - 0.3)^4$$ and write the answer as a decimal rounded to two places. 2. The formula involves evaluating a power of a difference inside parentheses, then multiplying by 9000. 3. First, calculate the value inside the parentheses: $$1 - 0.3 = 0.7$$. 4. Next, raise 0.7 to the 4th power: $$0.7^4 = 0.7 \times 0.7 \times 0.7 \times 0.7$$. 5. Calculate step-by-step: - $$0.7 \times 0.7 = 0.49$$ - $$0.49 \times 0.7 = 0.343$$ - $$0.343 \times 0.7 = 0.2401$$ 6. Now multiply by 9000: $$9000 \times 0.2401 = 2160.9$$ 7. The final answer rounded to two decimal places is $$2160.90$$.
