tolong di jawab ya butuh banget besok kumpul yang no 5&6 :)

5.
P1 = 2.000 Q1 = 5.000 kg
P2 = (40%×2000+2000)
= 800 + 2.000
= 2.800
Q2 = (25%×5.000+5.000)
= 1.250+5.000
= 6.250
/\Q = 6.250 - 5.000 = 1.250
/\P = 2.800 - 2.000 = 800

Elastisitas penawarannya :
= ((/\Q÷Q1) × 100%) ÷ ((/\P÷P1)×100%
=(1.250÷5.000×100%)÷(800÷2.000×100%)
= 25% ÷ 40%
= 0,625
jadi, besaran elastisitas penawarannya sebesar 0,625

6.
P1 = 500 Q1 = 1.000
P2 = (20%×500+500)
= 100 + 500
= 600
Q2 = (100+1.000) = 1.100

/\Q = 1.100 - 1.000 = 100
/\P = 600 - 500 = 100

Elastisitas penawarannya :
= ((/\Q÷Q1) × 100%) ÷ ((/\P÷P1)×100%
=(100÷1.000×100%)÷(100÷500×100%)
= 10% ÷ 20%
= 0,5

besaran elastisitas penawarannya sebesar 0,5 maka disebut penawaran inelastis
