1. Exercice 20
V0 = 12 000 Vn = 3000
2
A1 = Min 12000 × ; 12000 − 3000
5
= Min (4800; 9000) = 4800
→ V1 = V0 − A1 = 12000 − 4800 = 7200
2
A2 = Min 7200 × ; 7200 − 3000
5
= Min (2880; 4200) = 2880
→ V2 = V1 − A2 = 7200 − 2880 = 4320

2. Exercice 20 (suite..)
2
A3 = Min 4320 × ; 4320 − 3000
5
= Min (1728; 1320) = 1320
→ V3 = V2 − A3 = 4320 − 1320 = 3000
2
A4 = Min 3000 × ; 3000 − 3000
5
= Min (1200; 0) = 0
→ V4 = V3 − A4 = 3000 − 0 = 3000

3. Exercice 20 (suite..)
2
A5 = Min 3000 × ; 3000 − 3000
5
= Min (1200; 0) = 0
→ V5 = V4 − A5 = 3000 − 0 = 3000
