Grass seed A is worth $2.50 per pound and seed B is worth $1.75 per pound. How much of each would you use in order to make 75lbs of a mixture worth $2.14 per pound?

A: suppose use seed A with x pound and seed B with y pound.
then x+y=75 and 2.5x+1.75y=2.14*75
then x=39 and y=36
so I will use seed A with 39 pound and seed B with 36 pound
