\( 12 + (6 \times 4) \div 2 \)
12 + 24 ÷ 2 → 12 + 12 = 24
\( [5 \times (8 - 3)] + 14 \)
[5 × 5] + 14 → 25 + 14 = 39
Decimal Precision

Multi-Step Solutions
Investigation A (Laptops):
1. Laptops: 24 × 1,245 = $29,880
2. Pads: 24 × 12.50 = $300
3. Total: $29,880 + $300 = $30,180
4. Budget Check: 35,000 > 30,180. YES
5. Difference: 35,000 - 30,180 = $4,820 remaining.
Investigation B (Sauce):
1. Initial: 2.5 + 0.85 + 1.4 = 4.75 liters
2. Evaporation: 4.75 - 0.32 = 4.43 liters
3. Addition: 4.43 + 0.5 = 4.93 liters final volume.

Problem A (Garden):
1. Tomatoes: 1/4 of 480 = 120 sq ft
2. Cucumbers: 1/3 of 480 = 160 sq ft
3. Total Used: 120 + 160 = 280 sq ft
4. Remaining: 480 - 280 = 200 sq ft
5. Per Plot: 200 ÷ 2 = 100 sq ft
Problem B (Museum):
1. Adults: 3 × 14.50 = $43.50
2. Children: 8 × 9.25 = $74.00
