Jawaban:

perusahaan pertama pakai deret aritmatika, perusahaan kedua pakai deret geometri

perusahaan pertama :

a = 75.000 b = 10.000

[tex]sn = \frac{n}{2}(2a + (n - 1)b)[/tex]

[tex]s7 = \frac{7}{2} (2 \times 75.000 + (7 - 1)10.000) \\ s7 = \frac{7}{2}(150.000 + 6 \times 10.000) \\ s7 = \frac{7}{2} \: \times 210.000 \\ s7 = 735.000[/tex]

perusahaan kedua

a = 10.000 r = 2

[tex]sn = \frac{a( {r}^{n} - 1) }{r - 1} [/tex]

[tex]s7 = \frac{10.000( {2}^{7} - 1) }{2 - 1} \\ s7 = \frac{10.000 \times 127}{1} = 1.270.000[/tex]

kesimpulan : pilih perusahaan kedua, total gaji lebih besar
