Answer: - 7 5/8 is greater
Step-by-step explanation:
Basically, you are asked to find the equation for total revenue. In economics, total revenue is equal to the the quantity multiplied with price.
Total Revenue = Price*Quantity
Thus,
R(x) = P(x) * N(x)
R(x) = (0.6x + 5)(<span>−0.2x</span>³<span> + x</span>²<span> − 2x + 9)
R(x) = -0.12x</span>⁴ + 0.6x³ - 0.12x² + 5.4x - x³ + 5x² - 10x + 45
<em>R(x) = -0.12x⁴ - 0.4x³ + 4.88x² - 4.6x + 45</em>
