Answer:
30 ounces of iodine worth 80 cents an ounce
Step-by-step explanation:
Let
x ----> ounces of iodine worth 80 cents an ounce
we know that
The ounces of iodine (x) worth 80 cents an ounce mixed with 50 ounces of iodine worth 48 cents an ounce must be equal to the mixture (x+50) worth 60 cents an ounce
The linear equation that represent this situation is
[tex]0.80x+0.48(50)=(x+50)(0.60)[/tex]
solve for x
[tex]0.80x+24=0.60x+30\\0.80x-0,60x=30-24\\0.20x=6\\x=30\ ounces[/tex]
