Question

Cantitatea ceruta scade de la 400 la 200 bucati, atunci cand pretul creste de la 250 la
300.Coeficientul de elasticitate a cererii in raport de prêteste:
a) 2,5;
b) 2;
c) 1;
I
d) 4:
e) 0,5​

Answer 1

Q0 = 400

Q1 = 200

P0 = 250

P1 = 300

Ec/p = DeltaQ/ Delta P * P0/Q0

Ec/p = (Q1-Q0)/(P1-P0) * 250/400

Ec/p = (200-400)/(300-250) *5/8

Ec/p = -200/50 *5/8

Ec/p = -4 *5/8

Ec/p = -5/2

E/cp = -2,5
