Answer and Explanation:
The computation is shown below:
Fixed cost is
= $500,000 + $1,000,000
= $1,500,000
And, the marginal cost is
= $0.25 + $0.10
= $0.35 per paer
Now
as we know that
AFC = FC ÷ Q
Now for At 1,000,000 papers,
AFC is
= 1,500,000 ÷ 1,000,000
= $1.50/mo
At 800,000 , it would be
AFC = 1,500,000 ÷ 800,000
= $1.875/mo
MC = $0.35 per paper and the same is not changed
Now for break even, the average total cost is
ATC = AFC + AVC
ATC = FC ÷ Q + VC ÷ Q
VC = MC × Q
ATC = FC ÷ Q + MC
ATC = FC ÷ Q + 0.35
At Q = 1,000,000,
ATC = 1.50 + 0.35
ATC = $1.85
At Q = 800,000 , it would be
ATC = 1.875 + 0.35
= $2.225
As it can be seen that
The AFC changes from 1.50 to 1.875 which shows an increment of 0.375.
The MC remains constant or same at 0.35 as the printing and delivery costs per paper are remain same
And, The minimum amount that we must charge to break even rises i.e. from 1.85 to 2.225. That is a rise of 0.375
