How much of the $5 per poundcoffee will there be? ### Answer & Explanation Dominique Ferrell Beginner2022-07-28Added 18 answers type 1 coffee: sells for$4 per pound
type 2 coffee: sells for $8 per pound let x pounds of type 2 coffee is mixed with20 pounds of type 1 coffee to obtain a blend that will sell for$5 per pound.
selling price of type 1 coffee (20 pounds at a rate $4/pound) =20*4 = 80$
selling price of type 2 coffee (x pounds at a rate $8/pound) = x*8= 8x$
total coffee(type 1 + type 2) = (20 + x)pound if the blend sells for 5$/pound then selling price = 5*(20 + x) =100 + 5x$
so we can say,
100 + 5x = 80 + 8x
$⇒8x-5x=100-80=20$
$⇒3x=20$
$⇒x=20/3=6.67$
Answer: 6.67 pound of type 2 coffee(that sells for \$8 per pound)
