Step 1: Find the decrease in cost.
Decrease = Original cost - New cost
Decrease = sh 30 - sh 18
Decrease = sh 12
Step 2: Calculate the percentage decrease.
Percentage Decrease = (Decrease / Original cost) × 100%
Percentage Decrease = (sh 12 / sh 30) × 100%
Percentage Decrease = (12/30) × 100%
Percentage Decrease = (2/5) × 100%
Percentage Decrease = 0.4 × 100%
Percentage Decrease = 40%
