Selling price per pound = $3.64
Selling price for 10 pound = $3.64 x 10 = $36.40

Assumed all peanuts,
Total price = 10 x 2.20 = $22

Difference in total price = 36.40 - 22 = 14.40
Difference in price between peanuts and cashews = 5.80 - 2.20 = 3.60

Find number of pounds of cashews
14.40 ÷ 3.6 = 4 pounds of chashews

10 - 4 = 6 pounds of peanuts

Ans: He must mixed 6 pounds of peanuts with 4 pounds of cashew
