Jika, Y1=100 y2=120
C1=95 c2=110

Dit;
1. tentukan fungsi komsumsi :f (c)
2. tentukan fungsi tabungan f(f)
3. hitung besarnya pendaatankalimat (y) pada saat BEP
4. gambarkan kurva
jawab :
APC1 = c = 95 = 0,95
Yd 100
MPC = c = 110 = 0,92
Y 120

MPC ∆c = 110-95 =15 =0.75
∆y 120-100 20

Maka a : (APC-MPC) y
: (0,95-0,75) 100
: 20

1. fungsi komsumsi f (c) = a + by
20 + 0,75y

2. y = c + s
s = y-c  c = a + by
s = y – ( a + by)
s = y – (20 + 0,75y)
s = y – 20 – 0,75y
s = y- 0,75 Y-20
s = 0,25y – 20
s = -20 + 0,25y

3. BEP = y-c 0  c = y
= y – ( a + by)
= y – (20 + 0,75y)
= y – 20 – 0,75y
= 0,25y – 20
= -20 / 0,25 = 80
