# How many pounds of seed worth $1.05 per pound must be mixed with 30 pounds of seed worth $0.90 per pound in order to produce a mixture to sell for $1.00 per pound?

60

Let x pounds of seed to be mixed. Worth of x pounds seed = $1.05 x.

Worth of 30 pounds of other seed = $0.90 x 30 =$27.00.

Now worth of mixture i.e. ( x + 30 ) pounds = $1.00 ( x + 30).

As for the query,

$1.00( x + 30) =$1.05 x + $ 27.00
