Question 50229
Grass seed A costs $2 per pound, and grass seed B costs $4 per pound.  If a mixture of 10 pounds costs $24, find the amount of each type that was mixed?
-------------
Let amount of $4 seed be "x" pounds.
Value of that seed of 4x dollars.
Amount of $2 seed is "10-x" pounds.
Value of that seed is 2(10-x)= 20-2x dollars.
Amount of mixture = 10 pounds
Value of the mixture = 24 dollars.
EQUATION:
value + value = 24 dollars
4x + 20-2x= 24
2x=4
x=2 pounds ( amount of $4 seed)
10-x = 8 pounds (  amount of $2 seed)
Cheers,
