C Correct answer
Explanation

Statement 1 gives the current price. Statement 2 gives the rate of change. Both are needed to calculate the specific percentage decrease required when the price doubles.

AI explanation

Statement (1) provides the initial price of one dollar, which does not explain how sales volume changes. Statement (2) establishes a relationship between price increases and sales decreases, but lacks the actual starting price to calculate the specific drop for a price doubling. You must combine both statements to know that doubling the price from one dollar to two dollars is a 1 dollar increase, which equals four increments of 0.25 dollars, resulting in a 40 percent decrease in magazines sold.
