If a PCB design complexity doubles the cost per layer from $5 to $10, what is the new total cost for 3 layers?
If a PCB design complexity doubles the cost per layer from $5 to $10, what is the new total cost for 3 layers?
medium📝 Formula Result Q5 of 15
Step-by-Step Solution
Solution:
Step 1: Calculate new cost per layer
Cost per layer doubles from $5 to $10.Step 2: Multiply by number of layers
3 layers * $10 = $30 total cost.Final Answer:
$30 -> Option AQuick Check:
New cost = 3 * 10 = 30 [OK]
Quick Trick: Double cost per layer then multiply by layers [OK]
Common Mistakes:
MISTAKES- Using old cost per layer
- Adding instead of multiplying
- Ignoring doubling effect
