Answer:
Operate mine 1 four 4 days and mine 2 during 6 days to obtain minimum cost for the desired output of 850 gold and 18,000 silver
Explanation:
We generate the equation system on excel:
(50g + 3000s) Q_1 --> output generated on Mine 1
(75g + 1,000s) Q_2 --> output generated on Mine 2
12,000 Q1 + 17,000 Q2 = cost of the mines
we do solver to minimize the days of each mine considering a desired output of 18,000 silver and 650 gold:
and get the following:
M1 4 days output: (50g + 3000s) 4 = 200 g 12,000s
M2 6 days output: (75g + 1,000s) 6 = 450g 6,000s
Cost: 12,000 x 4 + 17,000 x 6 = 150,000
