Bonsoir
1a) M = 20 € et P = 26€
1b) M = 20 + (40 x 0.5) =
40€
P = 26 + ( 40 x 0.3) =
38€
2a) = 0.50 x + 20
2b) = 0.30 x +26
4) 0.50x +20 = 0.30 x +26
0.5 x - 0.3x = 26 -20
0.2x = 6
x = 30
pour 30 minutes, les 2 tarifs sont équivalents
0.30x + 26 < 0.50x +20
0.30x -0.50x < 20 -26
- 0.2 x < -6
x >30
Au delà de 30 minutes, la formule P est plus intéressante
