Explicație pas cu pas:
a)
S = suma achitata de un elev
transport 24S/100 = 6S/25
rest S - 6S/25 = 25S/25 - 6S/25 = 19S/25
taxa de statiune 1/38*19S/25 = S/50
rest 19S/25 - S/50 = 38S/50 - S/50 = 37S/50
37S/50 = 148 lei
S = 50*148/37 = 200 lei
b)
taxa de statiune 200/50 = 40 lei
% = (40/200)*100 = 20%
