A company sells seed either by the pound or by the acreage planted. It will sell seed M for no less than $5.50 a pound or for no less than $12.75 per acre planted. Farmers will pay no more than $6.25 a pound and no more than $13.50 per acre planted and always choose the price structure that results in the lowest cost per acre. If it takes 2 pounds of seed M to plant an acre of loamy soil and 3 pounds to plant an acre of clay soil, what is the range in dollars per pound, x, within which sales of seed M could take place?

(A) $4.25 ≤x ≤ $5.50
(B) $4.25 ≤x ≤ $6.25
(C) $4.50 ≤x ≤ $6.25
(D) $5.50 ≤x ≤ $6.75
(E) $5.50 ≤x ≤ $13.50
