Final answer:
Hunter needs to purchase 3 ounces of seeds and 7 ounces of dried fruit for his 10 oz mixed snack.
Step-by-step explanation:
Hunter needs to determine how much seeds and dried fruit to purchase for a 10 oz snack mix. We will create two equations based on the total cost and total weight.
Equation 1 (total weight): x + y = 10
Equation 2 (total cost): 1.50x + 2.50y = 10 × 2.20
Substituting '10 - x' for 'y' in Equation 2 gives us: 1.50x + 2.50(10 - x) = 22. After simplification, the equation becomes 1.50x + 25 - 2.50x = 22, leading to -1.00x = -3. Solving for 'x', we get x = 3 oz of seeds and y = 7 oz of dried fruit.
