Explanation / Answer

(1)

Marginal cost (MC) = Change in Total cost (TC) / Change in output (Q)

Marginal revenue (MR) = Change in Total revenue (TR) / Change in output (Q)

Therefore:

(2) Firm will maximize profit by equating MR with MC. When MR = MC = $8,

Quantity = 6 units

(3) Price = TR / Q = $8 / 1 = $16 / 2 = $24 / 3 =........= $56 / 7 = $8

Q TC ($) MC ($) TR ($) MR ($) 0 8 0 1 9 1 8 8 2 10 1 16 8 3 11 1 24 8 4 13 2 32 8 5 19 6 40 8 6 27 8 48 8 7 37 10 56 8
