Small number is three and large number is four
Answer:
Reorder point = (weekly demand * lead time) + (Z * standard deviation * √lead time) = (294 * 10) + (2.326 * 90 * √10) = 2,940 + 661.99 = 3,602 units
Old safety stock = Z * standard deviation * √lead time = 662 units
new safety stock = 331
331 = Z * 90 * √10
Z = 331 / 284.60 = 1.163
Using Normal distribution function, the new confidence interval is 87.76%
Answer:
Contribution margin ratio = 1 - variable cost ratio
= 25%
(a) 
= 1,400,000
= 25,000
(b) For profit of $42,000,
= 1,568,000
= 28,000
(c) variable cost = sales price × variable cost ratio
= $56 × 75%
= $42
New contribution margin = 
New contribution margin = 
= 0.4
= 40%
= $875,000
= 12,500
