(Round your unit answers to a whole number before calculating the breakeven point and round the break-even point to the nearest whole number.) b. If the sales mix changes to 1:4 (one chair sold for every four bar stools sold), what is the break-even point in dollars of sales? In units of chairs and bar stools? (Round your unit answers to a whole number before calculating the breakeven point and round the break-even point to the nearest whole number.)
