Answer:
It will charge $ 2.23 per papper to break even at 800,000 units
Step-by-step explanation:
fixed cost:
manufacturing cost: 500,000
labor fixed cost: 1,000,000
variable printing cost: 0.25
variable delivery cost: 0.10
total variable cost: 0.35
At which selling price the company break-even at 800,000 papers sales per month:


Contribution Margin Ratio: 1,500,000/800,000 = 1.875
Each units must contribute 1.875 dollars to payup the fixed cost.

S - 0.35 = 1.875
S = 1.875 + 0.35 = 2.225
As it cannot charge half-cent we will round up:
At 2.23 cent per papper the company will break even.
