Pure tin was mixed with a 4% tin alloy to produce an alloy that was 16% tin. How much pure tin and how much 4% alloy were used to produce 32kg of 16% alloy?
Answer provided by our tutors
let
x = kg of pure 100% tin
y = kg of 4% tin
x + y = 32
1.00*x + 0.04y = 0.16*32
by solving the above system of equations we find:
x = 4 kg
y = 28 kg
