When I try to prepare a quotation, how opportunity cost will

The opportunity will equal to the "profits" that you may earn from another project if you do not do this project. Say, if you bid for this project and needs 10 days to finish and say you currently has another project that may need the same 10 days and this second project can earn you profits of $100 then if you give up doing this project and do the first one instead then you will have an opportunity cost of at least $100. In other words, you will need to make at least $100 from the project that you are bidding in order to make sure that you are not losing money. On the other hand, if you currently have no work in hand, then there will not be any opportunity cost as you are currently not earning any money and hence you are not giving up any money to do this project.

YOUR OPPORUNITY COST IS YOUR HIGHEST VALUE OPTION FORGONE.

FOR EXAMPLE : IF YOU DO NOT BIT THE PROJECT, YOU CAN STUDY, WATCH MOVIE, ACCOMPANY WITH YOUR GIRLFRIEND/BOYFRIEND, OR DO OTHER PROJECT, SLEEPING, TRAVELLING, ETC,

YOUR NEED TO ARRANGE THE PROPRITY FOR THE OPTION:
1) SLEEPING TIME
2) STUDY TIME
3) WATCH MOVIE
4)ACCOMPANY WITH YOUR GIRLFRIEND/BOYFRIEND,
5)DO OTHER PROJECT

YOUR OPPORTUNITY COSTS IS SLEEPING TIME, BECUASE THIS IS YOUR HIGHEST VALUE OPTION FORGONE.

IF YOU USE THE RESOURCE FOR BIT A PROJECT, FOR EXAMPLE A4 PAPER , TONER, TRAVELLING FEE, ETC, THIS IS TRANSACTION COSTS,
