1. A) Because you don't want to be stuck living with your parents until you are 30
2. B) Living and educational expenses
Reason:
I took a test very similar to this a few days ago, and I am a straight-A student.
Answer:
(a)
TC(q) [before expansion] = Fixed Cost + Variable Cost
= 750,000 + 1.25q
TC(q) [after expansion] = (750,000 + 350,000) + 0.75q
= 1,100,000 + 0.75q
(b) (i) q = 600,000
TC(q) [before expansion] = 750,000 + (1.25 × 600,000)
= 750,000 + 750,000
= 1,500,000
TC(q) [after expansion] = 1,100,000 + (0.75 × 600,000)
= 1,100,000 + 450,000
= 1,550,000
Since expansion will increase total cost, profit will fall ceteris paribus. So firm should not expand.
(ii) q = 800,000
TC(q) [before expansion] = 750,000 + 1.25 × 800,000
= 750,000 + 1,000,000
= 1,750,000
TC(q) [after expansion] = 1,100,000 + (0.75 × 800,000)
= 1,100,000 + 600,000
= 1,700,000
Since expansion will decrease total cost, profit will rise ceteris paribus. So firm should expand.
Answer:
option (c) $500
Explanation:
Data provided in the question:
Demand, D = 500 vats of fertilizers
Cost, C = $1
Ordering costs for a new order, F = $250
Now,
Economic Order Quantity = 
on substituting the respective values, we get
Economic Order Quantity = 
or
Economic Order Quantity = √250,000
or
Economic Order Quantity = 500
Cost of Economic Order Quantity = 500 × $1 = $500
Hence,
the answer is option (c) $500
