QUESTION 13 + Amy drinks 5 capsules of coffee every week (assuming 50 weeks in a year). Each capsule costs S1, and the delivery fee is $5 per order. The annual holding cost rate is 20%. The coffee manufacturer provides a special offer the price of each capsule becomes $0.98 if the order quantity is at least 80 capsules. Amy, therefore, conducts the following analysis: STEP 1: The EOQ without the discount is around 112 units, and the corresponding minimum ordering + holding cost is $22.36. STEP 2: The ordering + holding cost with the quantity discount is K*R/80 + h_new*80/2 = $23.47. STEP 3: The additional ordering + holding cost to get the discount offer is $23.47 - $22.36 = $1.11. STEP 4: The additional saving in the purchasing cost is R*($1 - $0.98) = $5. According to Amy's analysis, she decides the quantity = 80 to obtain the discount, but the decision is not optimal. Please choose the earliest step that Amy makes a mistake. Step 1 Step 2 Step 3 Step 4 QUESTION 14 John sells decorated eggs on Easter.
