Answer: the break-even quantity is 6944
Explanation:
Let x represent the break-even quantity.
Fixed costs of $25,000 per month are allocated to the felt-tip operation, and variable costs are 40 cents(40/100 = $0.4) per pen. This means that the total cost of producing x pens for the forth coming month would be
0.4x + 25000
if pens sell for $4 each, it means that the total revenue from selling x pens would be
4x
At the point of break even, the total cost = total revenue
Therefore,
4x = 0.4x + 25000
4x - 0.4x = 25000
3.6x = 25000
x = 25000/3.6
x = 6944 to the nearest whole number
