The average rate of change expected in the sales when the amount spent on advertising increases from $50 to $100 is 82.5.
To find the average rate of change in sales when the amount spent on advertising increases from $50 to $100, we need to calculate the difference in sales (S(x)) between these two advertising amounts and divide it by the difference in advertising amounts.
First, let's find the sales at $50 and $100:
S(50) = -0.003(50)³ + 0.58(50)² - 200 = -75 + 1450 - 200 = 1175
S(100) = -0.003(100)³ + 0.58(100)² - 200 = -300 + 5800 - 200 = 5300
Now, we can calculate the average rate of change:
Average rate of change = (S(100) - S(50)) / (100 - 50)
= (5300 - 1175) / 50
= 4125 / 50
= 82.5
Therefore, the average rate of change expected in the sales when the amount spent on advertising increases from $50 to $100 is 82.5. Since none of the given options match this value, the answer is e. None of the above.

13 If the price elasticity of demand is 2.0, and a firm raises its price by 10 percent, the total revenue will... a. Not change. b. Fall by an undeterminable amount given the information available. c. Rise. d. Fall by 20 percent.
Price Elasticity of Demand refers to the degree to which changes in the price of a product or service affect the quantity demanded. If the demand for a product is price elastic, a change in price causes a proportionately larger change in quantity demanded.
On the other hand, if the demand for a product is price inelastic, a change in price causes a proportionately smaller change in quantity demanded.When the price elasticity of demand is 2.0 and a firm raises its price by 10%, the total revenue will fall.
The answer is letter D. The total revenue will fall by 20%. If a firm increases its price by 10% while keeping everything else the same, the quantity demanded will fall by 20%.Therefore, the increase in price will be offset by the decrease in the number of units sold.
