tolong bantu yaaaa plis buat besok senin..... secepatnya makasihh

P (6,4), Q (4,3), R ( 2,2), S (4,0), T (6,0)
fungsj sasaran 4x + 5y
P(6,4) ==> 4.6+5.4 = 24+20=44
Q(4,3) ==> 4.4+5.3= 16+15= 31
R(2,2) ==> 4.2+5.2 = 8+10 = 18
S(4,0) ==> 4.4+5.0 = 16+0 = 16
T(6,0) ==> 4.6+5.0 = 24 +0 = 24
Jadi nilai minimum 16, terjadj di S (4,0)
