Final answer:
The correct answer is Option A) D = 2N. In the given problem, the number of nickels is twice the number of dimes. The equation that represents this relationship is D = 2N.
Step-by-step explanation:
The correct answer is Option A) D = 2N.
In the given problem, the number of nickels is twice the number of dimes. Let's assume the number of dimes to be x. Therefore, the number of nickels would be 2x.
So, the equation that represents this relationship is D = 2N, where D represents the number of dimes and N represents the number of nickels.
