Answer:
The equation for this would be 2d+3 where d is the money spent in dollars.
Step-by-step explanation:
I'm not sure if this is what you where looking for, if not perhaps elaborate on what the question is.
How I got this equation:
For every dollar he gets 2 candies. So you would multiply 2 by the number of dollars. (2d) He also gets 3 more candies per purchase, you add three regardless of money spent, so 3 is added. (+3)
Giving you: 2d+3
