Pour le pantalon
prix 29 euros remise 15 %
montant de la remise 29x15% = 4 .35 euros
nouveau prix : 29-4.35 = 24.65 euros
pour la chemise
prix avt les soldes : 22 euros
remise : 4.4 euros
nouveau prix : 22 -4.4 = 17.60
donc remise en % : 22* x = 4.4
x = 4.4 /22 = 0.2 = 20 %
pour la veste
nouveau prix : 55.20
remise en % : 20
prix initial - (20% prix initial ) = 55.20
pi - 0.2pi = 55.20
0.8pi = 55.20
pi = 55.20 /0.8
pi = 69 euros
donc remise 69 x 20% = 13.80
