Given:
Manufacturing cost : fixed cost = 8,000 ; variable cost = 15 per mug
Selling Price: 35 per mug
Let x be the number of mugs.
Sales Revenue = 35x
Manufacturing Cost = 8,000 + 15x
Profit = Sales Revenue - Manufacturing Cost
P = 35x - 8,000 - 15x
P = 20x - 8,000
Break even level: Profit is 0
Sales Revenue = Manufacturing cost
35x = 8,000 + 15x
35x - 15x = 8000
20x = 8000
x = 8000/20
x = 400
Company must produce at least 400 mugs to break even or have 0 profit. Quantity greater than 400 will result to a profit while quantity lesser than 400 will result to a loss.
