1. Rumus Paket Gaji Firma Hukum
Komponen gaji :
- Gaji pokok: 1,2 x N
-
Bonus pengalaman: 3000 X E
-
Bonus usia (di atas 21 tahun): 1000X (A-21)
-
Formula Total Gaji (S):
- S= 1,2N + 3000E + 1000(A – 21)
- Perhitungan untuk Kasus Spesifik:
-
A = 30
-
E = 5
-
N = 150.000
-
S = 1,2(150.000) + 3000(5) + 1000(30 – 21)
-
S = 180.000 + 15.000 + 1000(9)
-
S = 180.000 + 15.000 + 9.000
- S = 204.000
2. Menuliskan Rumus Situasi
a) Biaya Plumber (C):
b) Penukaran Mata Uang (C): Karena 1 \text{ dollar} = 0,8 \text{ euro}, maka untuk mendapatkan X euro, Anda butuh $\frac{x}{0,8}$ dollar.
C = 10 + \frac{x}{0,8} \text{ atau } C = 10 + 1,25x
c) Total Jam Pelatihan (H):
H = 5a + 10b
d) Sewa Mobil (X):
X = Cd + cm
3. Evaluasi Bilangan Bulat (Tanpa Kalkulator)
Operasi Perkalian/Pembagian:
(A) 10 X (-2) = 20
(B) (-1) X (-3) =3
(C) (-8) : 2 = -4
(D) (-5) :(-5) =1
(E) 24 : (-2) = -12
(F)(-10) X (-5) = 50
(G)(g) (-6) X 5 X (-1) = -30 X (-1)=30
Operasi Penjumlahan/Pengurangan:
-
(a) 5 – 6 =-1
-
(b) -1 – 2 = -3
-
(c) 6 – 17 = -11
- (d) -7 + 23 =16
-
(e) -7 – (-6) = -7 + 6 = -1
-
(f) -4 – 9 =-13
-
(g) 7 – (-4) = 7 + 4 = 11
-
(h) -9 – (-9) = -9 + 9 = 0
-
(i) 12 – 43 =-31
-
(j) 2 + 6 – 10 = 8 – 10 =-2
4. Evaluasi Campuran (Urutan Operasi/BODMAS)
-
(a) 5 X 2 – 13 = 10 – 13 = -3
-
(b) 5 X (1 – 4) = 5 X (-3) = -15
-
(c) 1 – 6 X 7 = 1 – 42 =-41
-
(d) -5 + 6 : 3 = -5 + 2 = -3
-
(e) 2 X(-3)^2 = 2 X 9 = 18
-
(f) -10 + 2^2 = -10 + 4 = -6
-
(g) (-2)^2 – 5 X 6 + 1 = 4 – 30 + 1 = -25
5. Menyederhanakan Ekspresi Aljabar
-
(a) 2 X P X Q = 2PQ
-
(b) I X 8 = 81
-
(c) 3 X x X y = 3xy
-
(d) 4 X q X w X z = 4qwz
-
(e) b x b =b2
-
(f) k 3 x k = 3k2
