Final answer:
The correct statement defining a portion of the timeline for AB tools is: At year four, there is a cash outflow of $1,180.
Step-by-step explanation:
The timeline for AB tools can be summarized as follows:
- At year zero (time zero), there is a cash inflow of $500, represented by the initial deposit into the savings account.
- At year one, there is no specific information given about a cash inflow or outflow of $200, so option (a) is incorrect.
- At year two, there is no specific information given about a cash outflow of $800, so option (d) is incorrect.
- At year three, there is a cash outflow of $200, represented by the withdrawal from the account.
- At year four, there is a cash outflow of $1,180, represented by the withdrawal of the entire balance from the account.
Therefore, the correct statement defining a portion of the timeline is option (b): At year four, there is a cash outflow of $1,180.
