In today class, we continued talking about the flow diagram - In this example, we drew a flow diagram for 2 alternative A and B to see which one has the higher cost - This model above did not represent true the reality, so we calculated Present/Annual/Future cost/worth to see which will give us the better "investment" between A and B -These were basically what we learned in today class, then we moved on the study guide for final exam, bridge rules.
