If the cost of electricity to produce magnesium by the electrolysis of molten magnesium chloride is $155 per ton of metal, what is the cost of the electricity necessary to produce 10 tons of aluminum?

$1550

Step-by-step explanation:

Given the price of mgCl per ton of metal to be $155, that is;

1 ton of metal = $155

To find the cost of 10 ton of alumininum, we will say;

10 ton of aluminum = x

Equating both expressions;

1 ton of metal = $155

10 ton of aluminum = x (note that aluminum is a metal)

Cross multiply;

1 * x = 155 * 10

x = 1550

Hence 10 tons of aluminum will cost $1550

the answer is d. (1.2, -4.7) on edgn

hope this !
