Bonsoir,

1)

a) E = 25 x  n  = 25n

Enzo paye E = 25n.

b) M= 100 + 15 x n = 100 + 15n

Maya paye M = 15n + 100.

2)

a) Pour n = 8

25n = 25 x 8 = 200 € --> Enzo

15n + 100 = 15 x 8 + 100 = 220 € --> Maya

b) Pour n=10  

25n = 25 x 10 = 250 € --> Enzo

15n + 100 = 15 x 10 + 100 = 250 € --> Maya

c) Pour n = 15

15n =  25 x 15 = 375 € --> Enzo

15n + 100 = 15 x 15 + 100 = 325 € --> Maya.
