tolong no 36 saja pake cara ya

Q2-Q1/P2-P1 X P/Q = 22-20/15.000-10.000 x 10.000/20=20.000/100.000=0.2 (inelastis) ED<1

Q1 = 20
P1 = 10.000
Q2 = 22
P2 = 15.000

Ed = ΔQ/ΔP × P1/Q1
Ed = (Q2 - Q1)/(P2 - P1) × P1/Q1
Ed = (22 - 20)/(15000 - 10000) × 10000/20
Ed = 2/5000 × 10000/20
Ed = 0,2 (inelastis)
