Answer :
a. Equation: P * (vt)
You take the initial value (P) and multiply it by the amount added or subtracted to the account per year/month/day and the amount of years/months days. In your case, it would be a monthly basis. This would be the equation (with t equalling the amount of months passed): 4800 * (-400*t). Notice that v is negative because you are subtracting money.
b. I can't make a table of values on here, but just have x = the amount of months passed and y = the value after that many months

Answer:
A checking account is set up with an initial balance of $4800, and $400 is removed from the account each month for rent.
A: Let there be m months where $400 is removed from the account. And let x shows the amount of money left.
So, the equation becomes: [tex]x=4800-400m[/tex]
B: The table can form like:
m 1 2 3 4 5 6 7 8
x 4400 4000 3600 3200 2800 2400 2000 1600
