tolong kasih tau pake cara ny! makasih

S = {x|1≤x≤10, x = bilangan asli}
= 1,2,3,4,5,6,7,8,9,10

P = {x|1<x<6, x = bilangan prima}
= 2,3,5

Q = {x|1<x<9, x = bilangan genap}
= 2,4,6,8

Topi = T
Dasi = D

2T = 5D
T = 5/2 D

8T + 12 D = Rp. 64.000
8*(5/2)D + 12D = Rp. 64.000
20 D + 12D = Rp. 64.000
32D = Rp. 64.000
D = Rp. 2.000

8T + 12*(Rp. 2.000) = Rp. 64.000
8T = Rp. 64.000 - Rp. 24.000
8T = Rp. 40.000
T = Rp. 5.000

6T + 20D = 6*(Rp. 5.000) + 20*(Rp. 2.000)
= Rp. 30.000 + Rp. 40.000 = Rp. 70.000
