The margin of safety in units is calculated as the difference between the expected sales and the break-even sales. The break-even point in units is calculated as fixed costs divided by the contribution margin per unit (sales price per unit - variable cost per unit). Here, the contribution margin per unit is $780 - $470 = $310. The break-even point is $8370 / $310 = 27 units. The margin of safety is 60 - 27 = 33 units.
