o cámasá costá cát 2 perechi papuci
s-au cumpárat 25 de pulovere ,11 cámási si 28 de perechi papuci
au plátit 2800 lei

cát costá fiecare produs ?

25 pulovere costá cát 75 cámási
28 perechi papuci costá cát 14 cámási

rezultá 75+14+11=100 cámási costá 2800 de lei din care rezultá o cámasá costá 2800/100 =28 lei

1 cámasá ---- 28 lei
75 cámási ---- x lei
---------------------------
x = 75*28/1 = 75*28 = 2100 din care rezultá 25 pulovere costá 2100 lei

25 pulovere costá 2100 lei
1 pulover costá x lei
------------------------------------
x = 1*2100/25 = 84 deci un pulover costá 84 lei

28 perechi papuci costá cát 14 cámási
1 cámasá costá 28 lei
14 cámási costá x lei
-------------------------------
x = 14*28/1 =392 lei

dacá 14 cámási costá 392 lei deci rezultá cá 28 perechi papuci costá 392 lei

28 perechi papuci costá 392 lei
1 pereche papuci costá x
---------------------------------------------
x = 392/28 = 14

deci o pereche papuci costá 14 lei
un pulover costá 84 lei
o cámasá costá 28 lei
