a) there are 1/11 of the parts failed to use i.e. only 10/11 can used to re-assemble.
i.e. 143 x 10/11 = 130 pieces
b) average costs (per piece) = total costs / total pieces usesable
i.e. average costs = {1208400 + ($685x130) + (150 x 420)}/ 130
= (1208400 + 89050 + 63000)/130
= $10465
c) 25% profit of the costs = selling price
= $10465 (1 + 25%)
= $13081.25
marking price x 0.95 = selling price
marking price = 13081.25/0.95
= $13,769.74
d) 40% of 130 pieces can sold at marking price
= 40% (130) ($13,769.74)
= $716,026.48 (1)
60% of 130 pieces can sold at discounted price
= 60% (130)($13,081.25)
= $1,020,337.75 (2)
13 pieces sold at 5% of purchase price
= 13 (5%)($1,208,400/143)
= $5,492.73 (3)
total amount on whole transaction = (1) + (2) + (3)
= $1,741,856.96
