I realise I posted this in the wrong forum sorry this is grade
10 the problem is: a silversmith has alloys that contain 40%
silver and others that have 50% silver. A custom order requires
150g of 44% silver. How much of each alloy should be melted
together to make the bracelet? so far i got: Let x represent the
40% alloy Let y represent the 50% alloy. I rearranged the first
eqaution to be y=-x+150. Then subbed it into the second to be
0.4x+0.5(-x+150)=0.44 but when I solved this, i got 745.6. Where
did I go wrong?
