Q.

1.Diketahui:
N = 10
U = 3
R = 6
M = 12
A = 8
S = 2
A = 8
R = 5
I = 7

Ditanya;
N (U - S) +M(R + I) × N
=.......

..........
​

cara penyelesaian untuk soal ini 2, tergantung dari nilai R, yaitu 5 dan 6.

--------------------------------------------------------

cara pertama :

• = N (U - S) + M (R1 + I) × N
• = 10 (3 - 2) + 12 (5 + 7) × 10
• = 10 (1) + 12 (12) × 10
• = (10 × 1) + ((12 × 12) × 10)
• = 10 + (144 × 10)
• = 10 + 1.440
• = 1.450

--------------------------------------------------------

cara kedua :

• = N (U - S) + M (R2 + I) × N
• = 10 (3 - 2) + 12 (6 + 7) × 10
• = 10 (1) + 12 (13) × 10
• = (10 × 1) + ((12 × 13) × 10)
• = 10 + (156 × 10)
• = 10 + 1.560
• = 1.570

--------------------------------------------------------

HP = { 1.450, 1.570 }
