Pendant les soldes, un commerçant diminue le prix d'un blouson de 60% et note son nouveau prix : 80 euros
Calculer le prix du blouson avant les soldes ?
SVP, merci d'avance

Bonjour,
baisse de 60% = coef : 1-60/100 = 0,40
x = le prix initial
on sait que x*0,40 = 80
0,4x = 80
x = 80/0,4 = 200e
prix initial : 200e
