The only reason I joined this website is that I have this short assignment due tomorrow and I have no time to do it myself at all. At first it said pay now to view the full answer and there is nothing in the answers. This is such a scam. Please help if you can asap

An MJA engineer is a firm of consulting engineers. The business provides two main services: design and support services for civil engineering projects, such as the building of bridges and roads and environmental assessments for planned and existing developments. MJA is preparing a tender for a project involving the extension of the main runway at Adelaide Airport. An initial feasibility study recommended extending the western boundary of the airport by either shifting the major arterial road on the western boundary or building an underpass for the road beneath the extended runway. The tender involves assessing the economic and environmental feasibility of each alternative. MJA's tender manager is responsible for preparing tender bids. She estimates tender costs by identifying all costs that are likely to be direly associated with the project. To obtain the final tender bid, the total professional (engineering and scientist) labour costs are marked up by 75 per cent, and all other costs are marked up by 50 per cent. These margins are intended to cover any indirect cost plus provide the required profit margin on the project. The tender manager estimated the following direct costs for the airport project: Input Costs Civil engineers 100hours 21000$ Environmental scientists 80 hours 15000$ Support labour 100 hours 9000 Travel 500km 750 Computer time 40hours 3000 Photocopying,phone,tax 375 Required 1. Estimate the tender bid for the project 2. Estimate the profit on the project if the bid is successful and all costs are incurred as planned. 3. Once a project has begun, MJA will use a costing system that tracks all direct costs to projects. If the airport bid is successful, how would managers at MJA use this information? 4. Do you think there is likely to be any link between the costing system used to account for existing projects and the system that the tender manager uses to prepare bids for potential projects? Explain
