take engineering economics exam of 20questions for me online

Need an expert to help me do an engineering economics test which is due in 15hrs which is friday the 3rd at 11.59pm ET. Bid based on 20questions though it may be less. I have also attached a sample test to use as a guide and get idea of how test may be. Please be sure this is what you know and very good in before bidding. Pls bid only if you understand the whole concept in the sample test given And i can also be online to help for questions you are not very familiar with by looking thru my class notes or textbook. So it wil be combined effort, i want to make at least an 85-90, possibly 100.
