nlexa [21]

Answer:

D. 0.925x + 0.88y = 0.91(x + y)  

Step-by-step explanation:

The important point to remember is that the total mass of pure silver is the same on each side of the equation.

0.925x = mass of pure silver in first alloy

0.88  y = mass of pure silver in second alloy

The final alloy has a mass of (x + y) g and is 91 % pure silver, so

0.925x + 0.88y = 0.91(x + y)
