Answer: The relationship is m=20-2d. The relationship is negative.
Step-by-step explanation:
The relationship is m=20-2d (m is the amount of money in your bank and d is days). This is because the amount of money you have equals the 20 dollars you originally had minus 2xd or 2d (this is because you spend 2 dollars each day) The relationship is negative because you are subtracting/taking out money. Hope this helps!
