Followed by a longer discussion of more complex problems that the situation might entail.AnswerAdd TagsFlag as InappropriateFlag as InappropriateInterview Answers8 Answers▲3▼Actually, to correct the above response, if the selling price for 1 product is $794 (to cover the cost price of the product itself ($4) ), only 1 quantity needs to be sold. ($794 + $10) = ($800 + $4).Anonymous on Mar 14, 2018Flag as InappropriateFlag as Inappropriate▲2▼let's say we should sell y+1 units to break even 800 + 4.y = y*x + 10*y 800 = y(x + 10 - 4) 800/(x+6) = y so we should sell (800/(x+6)) + 1 unitsElif A. on Mar 10, 2022Flag as InappropriateFlag as Inappropriate▲4▼How is it possible to answer this without knowing the selling price per product? # of quantities to sell in order to breakeven depends on how much the selling price per product is? Since the selling price says X, you can sell it for $790 and breakeven by just selling 1 product ($790 per product + $10 annual fee (assuming it's per product)). But I may be misunderstanding the information provided. Any feedback?Anonymous on Mar 14, 2018Flag as InappropriateFlag as Inappropriate▲8▼Erin - it probably shouldn't be. The Revenue side should be (unit price + 10) * number of units sold. Dapo has assumed that unit price and number of units sold is the same since the letter X is used to describe both variables. That might be correct, but it would be an odd quirk of the question - I'd bet that you can ask what the unit price is.Andy on Sep 17, 2012Flag as InappropriateFlag as Inappropriate▲11▼Why is x^2?Erin on Feb 28, 2012Flag as InappropriateFlag as Inappropriate▲10▼Mostly algebra, basic economics, and common sense.Anonymous on Nov 8, 2010Flag as InappropriateFlag as Inappropriate▲10▼very good if all 3 of you are interviewing, I can get the position. It doesn't say the annual fee is per product, so you have to assume or ask if it is the case, and if not the # of customer and potential customers estimation. And that x^2 Dapo, did you pass the online test?Anonymous on Feb 13, 2014Flag as InappropriateFlag as Inappropriate▲19▼total cost= 4x + 800 total income= x^2 + 10x to break even: 4x + 800 = x^2 + 10x solving for x by evaluating the quadratic equation above, x ~= 25.45 To break even, 26 units must be soldDapo on Jul 6, 2011Flag as InappropriateFlag as InappropriateInterviews>Capital OneAdd Answers or CommentsTo comment on this, Sign In or Sign Up.
