Givean example of each (B) What are themain types of engineering economic decisions? Give anexample of each (c) Therearefive types of costthat we always consider in our engineering economics analysis, list all of them and support your answer with an example of each. Question 2 (20 Marks) (A) you are aboutto borrow $10,000 from a bank at an interest of 97o compounded annually, You are required to make five equal annual repayments in the amount of $ ? per year (Find the payment per year), with the first payment occurring at the end of year L Showthe interest payment andprincipal payment in each year. (B) For an interest rate of 127o compounded annually, find (a) How much canbe lent now if $ 10,000 will be repaid at the end of five years? (b) How much will be required in four years to repaya 25,000loan received now? Question 3 (20Marks) (A) Forthefollowing transactions, draw theC.F.D and find thevalue of G that makes the deposit series equivalent to thewithdrawal series at interest rate of 127o, compounded annually. (B) A local newspaper headline blared, "ShawnSmithSinged for $30 Million." A reading of the articlerevealed that on April 1 ,2009, ShawnSmith, the former record-breaking centre from HockeyUniversity, signed a $30 million package with the Edmonton Ice Knights. The termsof the contract were$3 million immediately,2.4 million per yearfor the first five years (with the first payment after one year),and $3 million per year for the next five years(with the first paymentat year6). If Shawn'sinterest rate is 87oper year, what would his contract at the time he sisns it. Question 4 (20 Marks) (A) You have borrowed $ 15,000 at an interest rateof 9Vo. Equalpayments will be made over 3-year period (first payment at the end of the first year). What will the annual payment be, andwhat will the interest payment be for the second year? (B) The following equation describes the conversion of a cash flow into an equivalent equal payment series with N = l0: A = [800 + 20(A/G,6%, 1)l x (P/A, 6Va, 7) (NP, 6Vo, 10)+ [300(F/ A, 67o, 3) - 5001(A/F, 67o,70) Reconstruct the originalcash flow diagram.

ECOR 16068Winter 2008/09 - Midterm Test Question 1: What outputu,ouid be produced by the codesnippet below?"i" and 'J" ate integer variables. i: i'i:7' ' *:-l 'l , whiie 0 <: fO { if (i%3::0) i cout << i << endl; l ) j:j+4; 4 ;':'j ) cout << j << endl; Question 2: Suppose we would like to replace the code shownbelow with codethat i) has EXACTLY the same effectbut that ii) makes use of a "do while" instead of a "while". Show how this canbe accomplished. while @<aQ { b:B+72'.a:a+1: ) Question 3: Write a C++ programthat reaCs in two integers and that then outprits all of the integers between the two values(including the valuesthemselves). The values must be output in ASCENDING order and eachvalue should appear on a separate line. Note that there is no guarantee that the first value entered will be smallerthanthe second (or vice versa). example: If 6 and 2 areinput the programshouldoutput. 6 / 3 A 5 6 Question 4: Write a programthat reads in threefloating point valuesand that outputs the greatest of these values. Question 5: The future value ofX dollars invested for I' yearsat l percent canbe found by applying the following equation: Value=X(1+11100)' Write a programthat reads in l and that then outputsa table giving the future value forXfrom $1000 to $5000 (in $1000steps) andY from 10 to 30 years (in 5 yearsteps). Future values must be output with two decimalplaces and the tablemust be formatted exactly as shown in the example below. Note that the column widths at the bottom areNOT part of the table but are simply thereto help you. Note: Funclton pow is useful here. pow(x, y) givesx to theyth power Exarnple: Enter t,he interest rate in percent: 5 1_000 t_0 1,628 .89 l_s 207I .93 20 2653.30 25 3386.35 30 432L.94 10 2000 3257.79 4L57.86 s306.60 6772.7I 8643.
