4 Kamar tipe A dan 5 Kamar tipe B
(4.3)+(5.4)
12+20
32
ada jawaban nya gk 9 itu?
3A + 4B = 32 org
3A + 4(3/2A) = 32
3A + 6A = 32
9A = 32
A= 32/9 = 3,56 = 4
(dibulatkan ke atas kalau ke bawah B> 3/2A)
3A + 4B = 32
3(4) + 4B = 32
12 +4B = 32
4B = 20
B = 20/4= 5
kamar A + Kamar B= 4+5= 9 Kamar
Cat :
Kamar Penuh
# 3A +4B = 3(4) +4(5)=12+20=32
# B < 3/2A
5 < 3/2x4
5 < 6
