The number of grams of tin in the alloy will be denoted by the conditional variable “Y”.
Given the information in this example, we form the following equation: Y = (140 / (7 + 3)) x 7.
As a result of solving this equation, we have the following value Y = (140/10) x 7 = 14 x 7 = 98 grams of tin.
Answer: The alloy contains 98 grams of tin.
