# Metal alloy

What is the ratio of metals in the alloy that is in the 50 tonnes of steel to 30 kg nickel?

Correct result:

x =  0.06 %
y =  99.94 %
p =  0.0006004

#### Solution:

x = 100-y
x = 30/(50•1000)•100
p = 30/(50•1000-30)

x+y = 100
x = 0.06
p = 0.0006

p = 3/4997 ≈ 0.0006
x = 3/50 = 0.06
y = 4997/50 = 99.94

Our linear equations calculator calculates it.
$p = \dfrac{ m(Ni) }{ m(Fe)} = \dfrac{ 30 }{ 50\cdot 1000-30} = \dfrac{ 3}{ 4997} = 0.0006004$
