Testing Fundamentals - Why Software Testing Matters

A$1200

B$800

C$100

D$1000

Step-by-Step Solution

Solution:

Step 1: Calculate design and maintenance costs
Design cost = 3 * 200 = $600; Maintenance cost = 8 * 200 = $1600.
Step 2: Find cost difference
Difference = Maintenance - Design = 1600 - 600 = $1000.
Final Answer:
$1000 -> Option D
Quick Check:
Cost difference = $1000 [OK]

Quick Trick: Subtract design cost from maintenance cost [OK]

Common Mistakes:

Adding costs instead of subtracting
Using wrong multipliers
Confusing design and maintenance costs
