medium📝 Formula Result Q5 of 15
Step-by-Step Solution
Solution:
Step 1: Calculate cost per PCB for 5-day delivery
$100 ÷ 50 PCBs = $2 per PCB.Step 2: Calculate cost per PCB for 10-day delivery
$70 ÷ 50 PCBs = $1.40 per PCB.Final Answer:
$1.40 per PCB for 10-day delivery -> Option BQuick Check:
Cheaper option = $1.40 per PCB [OK]
Quick Trick: Divide total cost by quantity to find per PCB price [OK]
Common Mistakes:
MISTAKES- Mixing total cost with per PCB cost
- Ignoring delivery time impact
- Incorrect division
