Wild rice sells for $6 pound, and plain rice sells for $1 per pound. A grocer wants 10 pounds if the mixture to sell for $2 per pound. How much of each type should he used?

wild rice needed  x lbs
plain rice needed  10x lbs
6x + 1(10x) = 2(10)
6x + 10x = 20
5x = 10
x = 2
he needs 2 lbs of wild rice and 8 lbs of plain rice
