Landmark Coal operates a mine. During July, the company obtained 500 tons of ore, which yielded 250 pounds of gold and 63,700 pounds of copper. The joint cost related to the operation was $500,000. Gold sells for $325 per ounce and copper sells for $0.89 per pound. Allocate the joint costs using relative weight. With these costs, what is the profit or loss associated with Copper?

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
