Answer:
$42,000
Step-by-step explanation:
Product __ pound ___ price/pound ____ value
Feed ___ 100000 ____ 0.70 ________ 70000
Flour ___ 50000 _____ 2.20 ________ 110000
Starch __ 20000 _____ 1.00 ________ 20000
Total value _____________________ 200000
In value basis :
Feed's percentage of total value :
(Feed value / total value) * 100%
(70000 / 200000) * 100%
0.35 * 100% = 35%
Feed percentage * joint cost
35% * 120,000 = 42,000
