STATUS : 100%
KETERANGAN : Saya telah mengerjakan tugas ini dengan baik dan benar
BUKTI :
1)
Formula total gaji:
S=(1.2N)+(3000E)+(1000(A−21))S = (1.2N) + (3000E) + (1000(A – 21))
Dimana:
-
AA = umur
-
EE = tahun pengalaman
-
NN = gaji sekarang
Kasus: A=30A = 30, E=5E = 5, N=150000N = 150000
S=(1.2×150000)+(3000×5)+(1000×(30−21))S = (1.2 \times 150000) + (3000 \times 5) + (1000 \times (30 – 21)) S=180000+15000+9000S = 180000 + 15000 + 9000 S=204000S = 204000
Jawaban: $204,000
