1. Total package price ÷ total rental hours
2. Hours used × price per hour
3. Package price − used amount = total refund
EXAMPLE
1. Total package price ÷ total rental hours
VIP 2 DAYS Rp28.000 ÷ 48 jam = ± Rp583/jam
2. Hours used × price per hour
17 jam × Rp583 ≈ Rp9.911 (Rp10.000)
3. Package price − used amount = total refund
Rp28.000 - Rp10.000 = Rp18.000
