To find: Thequantity of each type of dry fruits.

Answer to Problem 22P
The 15 pounds of each type of dry fruits should be used for the mixture.
Explanation of Solution
Given information:
Total quantity of mixture = 30 lb
Price of first type is $ 4.30 per pound and price of the other is $ 3.90 per pound.
Price of mixture is $ 4.10 per pound
Calculation:
Let, the quantity of first type of dry fruits be x pound and that of the other be y pound.
By question
From equation (1)
Substituting y in equation (2)
Therefore,
Therefore, 15 pounds of each type of dry fruits should be used for the mixture.
