The unknown quantity of kilograms of alloy required to obtain 54 kilograms of copper is denoted by the conditional variable “Y”.
Using the conditions of the example, we get the proportion: 100% relate to U kg of alloy, as 18% relate to 54 kg of copper.
Based on the conditions of the proportion, we form the equation: Y x 18 = 100 x 54.
As a result of solving the existing equation, we will have Y = 100 x 54/18 = 100 x 3 = 300 kg of alloy.
Answer: 300 kg of alloy.
