Answer :
Answer:
Note: The organized table is attached as picture below
i. What is the estimated equation for average variable cost (AVC)?
Intercept value = 43.40, Parameter estimates of Q and Q2 = -2.80 & 0.20 respectively.
Hence, the estimated equation for AVC is:
AVC = 43.40 - 2.80Q + 0.20Q2
ii. What is the estimated equation for total variable cost (TVC)?
Similarly, the estimated equation for TVC is
= AVC * Q
= 43.40Q - 2.80Q2 + 0.20Q3
iii. At what level of output is AVC at its minimum point for Straker Industries?
AVC will attain its minimum value when its derivative is set = 0. This occurs when:
-2.80 = -0.40Q
Q = 7.
iv. What is the estimated equation for short-run marginal cost (SMC)?
SMC is the derivative of TVC, its estimated equation is given by:
= 43.40 - 5.60Q + 0.60Q2
iv. If Straker Industries produces 20 units of output, what is its estimated TVC, AVC and SMC?
TVC = 43.40Q - 2.80Q^2 + 0.20Q^3
TVC = 43.40(20) - 2.80(20)^2 + 0.20(20)^3
TVC = 868 - 1120 + 1600
TVC = 1348
At 20 unit of output, its estimated TVC is 1348
AVC = 43.40 - 2.80Q + 0.20Q^2
AVC = 43.40 - 2.80(20) + 0.20(20)^2
AVC = 43.40 - 56 + 80
AVC = 67.4
At 20 unit of output, its estimated AVC is 67.4
SMC = 43.40 - 5.60Q + 0.60Q^2
SMC = 43.40 - 5.60(20) + 0.60(20)^2
SMC = 43.40 - 112 + 240
SMC = 171.4
At 20 unit of output, its estimated SMC is 171.4.
