500- 50=450
450:5=90 . alina
90+5=95 bianca
90+15= 105 corina
90+10=100 dinu
90+20=110 elena
A+B+C+D+E = 500 lei
A /----/
B /----/-5
C /----/-15
D /----/-10
E /----/-20
500 + (5+15+10+20) = 500+50 = 550
550 : 5 = 110 (un segment egal)
A = 110 lei (Alina)
B = 110-5= 105 lei (Bianca)
C = 110-15 = 95 lei (Corina)
D = 110-10 = 100 lei (Dinu)
E = 110 -20 = 90 lei (Elena)

110+105+95+100+90 = 500 lei
