Under the assumptions of the basic EOQ approach, to find the best order size when per unit price is fixed I need to balance:

Group of answer choices

Holding cost and ordering cost

Holding cost and purchase price

Ordering cost and selling price

Selling price and purchase price

If TC = Q/2 * H + D/Q * S then the derivative of TC with respect to Q is:

Group of answer choices

H/2 + DS/Q

H/2 + DS/Q^2

Q/2 + DS/Q

H/2 - DS/Q^2
