Use the following graph to answer the next questions, given that CM%=0.7 Hint: you may use any of the following equations to help find some answers: Total Revenues (TR)=SP per unit x # of Units sold Total Costs (TC)=FC+(VC per unit x # of Units sold ) X(Units)=CM/unitFC+NIX($)=CM%FC+NI 1. Calculate the following amounts: BEP($)= CM/unit = VC/ Unit = Net profit (loss) at 4,000 unit = Net profit (loss) at 1,600 units
