✔ 最佳答案
單利息既本利和公式係 P(1+r%n)=A本金係人都知係P
P(1+8%5)=4000
P(1.4)=4000
P=4000/1.4
P=20000/7 (真確值)
P=2857.1 (準確至小數點後一個位)

Let x be the principal,
P*(1+8%*5)=$4000
P=$4000/1.4
P=$2857 (correct to the nearest dollars)
P*(1+8%*5)=$4000
P=$4000/1.4
P=$2857 (correct to the nearest dollars)

let x be the money
x*(1+0.08*5)=4000
x=2857
x*(1+0.08*5)=4000
x=2857

Let y be 本金,
y x 8% x 5 = 4000
y x 40% = 4000
y=4000/0.4
y=100
本金=$100
y x 8% x 5 = 4000
y x 40% = 4000
y=4000/0.4
y=100
本金=$100
