Answer:
manufacturing cost per unit: $27.50
no fixed manufacturing cost: $20
gross margin: 40%
Step-by-step explanation:
selling price is 50$
total varible cost is 60% then, which is 30$
2.50 per unit
30-2.50= 27.50
selling price minus total variable cost
50-30=20
gross margin= gross margin/selling price x 100
20/50x100=40
40%
