Problem 4 Problem No 5 Problem 6 Step-by-step explanation: Given: Units, u = 400,000 units Cost of goods sold: variable = 70% fixed = 30% Operating expenses: variable = 60% fixed = 40% Cost of goods sold, C = $ 2,400,000 Operating expenses, O = $900,000 Sales, S = $4,000,000 Gross profit, G = $1,600,000 Net income, I = $700,000 Variable cost of goods sold, C1 = COGS × 70 % = $ 2,590,000 x 65% = 1,680,000 Variable cost per unit = Variable cost, C1/units = 1,680,000 / 400,000 = $4.2 variable cost per unit Variable Operating expenses, O1 = operating expenses, O × variable % = $900,000 x 60% =540,000 Variable operating expense per unit = variable operating expenses/units = 540,000/400,000 = $1.35 variable cost per unit Incremental analysis: Given: Number of kitchen gadget = 40,000 cost per 1 toaster = $6 Revenue, r = (40000 × 6) = $240,000 Cost of Goods Sold, Cs = variable cost per unit × units of toasters = (40,000 x 4.2) = $168,000 Operating Expenses, Os = (variable operating expenses per unit × units of toasters) + additional shipping costs = (40,000 x 1.35) + 8,000 = $54,000 + $8,000 = $62,000 Net Income, N = revenue, r - (cost of goods sold, Cs + operating expenses, Os) = $240,000 - ($168,000 + $62,000) = $10,000 B.
