Answer:
11.14 pounds ( approx )
Step-by-step explanation:
Let x pounds of poppy seeds and y pounds of clover seeds were mixed,
∵ Poppy seed costs 24$ per pound and clover seed costs 13.00$ per pound,
Thus the total cost of x pounds of poppy seeds and y pounds of clover seeds = 24x + 13y,
According to the question,
Resultant mixture costs $ 20.70 per pound,
∴ Total cost = 20.70(x+y),





If x = 26,

Hence, 11.14 pounds of clover seeds should be added.
