Final answer:
The question can be translated into the algebraic equation 6d = 72. By dividing both sides by 6, we find that Donnie's age, represented by d, is 12.
Step-by-step explanation:
The question is asking for an algebraic representation of Donnie's age. The statement The product of Donnie's age and 6 is 72 can be translated into an algebraic equation using variable d to represent Donnie's age.
This gives us the equation 6d = 72. To find Donnie's age, we can solve for d by dividing both sides of the equation by 6, which will yield d = 12.
