1. Ebony kept her bank account open for only 3 weeks, and the graph shows the entire 3 weeks. During that time, her greatest balance was $400.
(B) 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.

Answer 3

B(d) is a function of the number of days d since she opened the account.
so B(0) would be 0 days?

Answer 4

yes! B(0) is the balance at day=0
now, since the length of segment OA is half of the length of segment OB, and the length of segment OB is proportional to the max balance, namely $400, then the segment OA is proportional to 400/2=...?

Answer 5

200
