in prima zi s-au vandut: 34% - 12,05⇒ (34x-1205)/100
a doua zi : 1 si 1/2 + 0,(2)x, ⇒3/2 + 2x/9= (27 +4x)/18
a treia zi: 46,08(3) + 0,(6)
46,08(3) =(46083 -4608)/900=41475/900=553/12
0,(6) =6/9=2/3
deci a treia zi 553/12+2/3 [34x-1205)/100 + (27+14x)/18]
=(105435 +1012x)/2700
deci
(34x-1205)/100 + (27 +4x)/18 + (105435 +1012x)/2700 = x
de aici se scoate x
