Answer 1

1. a. 2x + 5y = 38.500
b. anggur = 3.salak =  x  = 3y ; anggur = 3y
       2x + 5y = 38.500
<=> 2(3y) + 5y = 38.500
<=> 6y + 5y = 38.500
<=> 11y = 38.500
<=> y = 3500
anggur =3500 x 3 = 10500
Salak=3500
c. 3 kg anggur + 4 kg salak = (10500 x 3) + (3500 x 4) = 45500

Answer 2

K= 2(p+l)
60=2(p+p-6)
60=2(2p-6)
60=4p-12
60+12=4p
72=4p
p=18

L=p.l
=18.(18-6)
=18.12
=216
