ACCOUNTING AND FINANCIAL ENGINEERING - ANSWER 34.23 : (a) Income = 10000 units x $10 / unit = $100000. (b) Overall cost of production = overall variable cost + overall fixed cost = 10000 units x $2 / unit + $30000 = $50000. (c) Percentage of gross profit = 100 x [ answer (a) - answer (b) ] / [ answer (a) ] = 100 x ($100000 - $50000) / ($100000) = 50 %. (d) Let N units x $10 / unit = $50000 = answer (b) where N = units successfully sold = $50000 / ($10 / unit) = 5000 units. (e) Let contribution margin = (selling price - variable cost) / unit = $ (10 - 2) = $8. M x (contribution margin) = overall fixed cost = $30000. M = ($30000) / ($8) = 3750 units need to be produced at minimum.

Question 109 - (a) Acceptable wavefunction in quantum mechanics in the range of : negative infinity < x < positive infinity, vanishes at least at one boundary. Which of the following is the wavefunction or are the wavefunctions of acceptable theory : P = x, P = | x |, P = sin x, P = exp (-x), P = exp (-| x |)? State the reason. (b) Let linear momentum operator P = -ih d / dz. The wavefunction is S = exp (-ikz) where i x i = -1, k and h are constants. Find the linear momentum of such wavefunction by using the term P x S.
