D8 = 1 Question 1 [Total 10 marks] Suppose you are studying Engineering in HKCC and you cannot come to the campus to have face-to-face lesson due to the latest pandemic situation. You have to attend online lessons using Microsoft Teams meeting, but unfortunately your laptop computer suddenly died on you this morning. You have to decide what to do to solve your problem. - A rag man (4) who sometimes show up in your neighborhood offers you $ (100 + D8x10) for your broken computer. Your computer is quite new, but the 1-year warranty period for your computer has just expired. If you want to repair your computer, it is expected to cost you $ (1,000 +D8*100) to get it fixed. Or you may want to buy a new computer. The price for the same model is $7,100 with no trade-in offer while that of the new model is $10,000 with $ (200 +D8x10) trade-in offer with your broken computer. You have only $ 7,000 in your savings account and do not have any credit card. Assume your parents won't pay any extra money to help you buy a new computer. You need to manage your own money. If you get your laptop computer fixed, you can sell it in the online second-hand marketplace for $ (4,000 + D8x100). Apply the first three steps of the 7-step Engineering Economic analysis procedure to analyze your situation (a) In Step 1, clearly define your problem. (b) In Step 2, develop 3 feasible alternatives AND state 1 major assumption for each alternative. Don't repeat what have already been assumed. (c)- In Step 3, calculate the net cash flow of your savings for each alternative. k tt
