Explanation:

Step1: Solve Q13

Total cookies = 250. Chocolate chip (30%) + M&M (30%) = 60%. Peanut butter = 100% - 60% = 40%.
Peanut butter cookies = 250 × 40% = 250 × 0.4 = 100.

Step2: Solve Q14

Total jewelry = 150. Bracelets (20%) + earrings (10%) = 30%. Necklaces = 100% - 30% = 70%.
Necklaces = 150 × 70% = 150 × 0.7 = 105.

Step3: Solve Q15

Total money = $75. Fruit (20%) + vegetables (20%) + snacks (20%) = 60%. Meat = 100% - 60% = 40%.
Meat cost = 75 × 40% = 75 × 0.4 = 30.

Step4: Solve Q16

Total money = $150. Jacket (30%) + shoes (40%) = 70%. Saved = 100% - 70% = 30%.
Saved money = 150 × 30% = 150 × 0.3 = 45.

Answer:

1. 100
2. 105
3. 30
4. 45
