Question

A nursery sells grass seed A for $6.75 per pound and grass seed B for $5.50 per pound. The nursery sells a mixture of the two kinds of seeds for $6.25 per pound. Let x represent the amount of seed A the nursery uses in 5 pound of the mixture.

Answer 1

Explanation:

x(6.75) + (5 - x)(5.50) = 5(6.25)

6.75x + 27.5 - 5.50x = 31.25

1.25x = 3.75

x = 3 lb of seed A
