Question:   Give an estimate to the nearest hundreds for B(0)  . Explain how you determined your estimate and tell what B(0)   means in context of the situation.

B(0)   is the opening balance.....this appears to be ≈  $200

 

[ The graph at this point looks to be about 1/2 the height of the greatest balance of $400 ]
