Jadi uang Irna ialah Rp.21.000,00
Semoga Bermanfaat
Uang irna adalah i
Uang tuti = t
Dik:
i = 3/2t
i+t = 35000
Jwab:
i+t = 35000
3/2t+t = 35000
3/2t+2/2t = 35000
5/2t = 35000
5t = 35000 x 2
5t = 70000
t = 70000/5
t = 14000
Masukkan nilai "t" ke:
i = 3/2t
i = 3/2 x 14000
i = 21000
Jadi, uang irna sejumlah 21000
