| **The alloy contains 84% tin, 10% antimony, 4% copper and 2% bismuth. Find the mass of each of these metals in 150 kg of alloy.**

1) We define the tin mass in the alloy if it is 84% of all Masy.

150 – 100%;

X – 84%;

X = 84 * 150/100;

X = 126 kg.

2) We will find out the mass of antimony in the alloy if its 10%.

150 – 100%;

X – 10%;

X = 150 * 10/100;

X = 15 kg.

3) We define the mass of copper in this alloy if it is 4%.

150 – 100%;

X – 4%;

150 * 4/100;

X = 6 kg.

4) We will find out the mass of bismuth if it is 2%.

150 – 100%;

X – 2%;

X = 150 * 2/100;

X = 3 kg.

Answer: The alloy contains 126 kg of tin, 15 kg of antimony, 6 kg of copper and 3 kg of bismuth.
