✔ 最佳答案
Let the sum of money be yy(1+8%/2)4=146232.32
(1.04y)4=146232.32
1.04y=146232.32/4
y=36558.08/1.04
y=35152

Let the sum of money be $P.
P ( 1 + 8% / 2 )^(2x2) = 146232.32
P ( 1 + 4% )^4 = 146232.32
P x 1.04^4 = 146232.32
P = 146232.32 / 1.04^4
P = 125000
The sum of money is $125000.
P ( 1 + 8% / 2 )^(2x2) = 146232.32
P ( 1 + 4% )^4 = 146232.32
P x 1.04^4 = 146232.32
P = 146232.32 / 1.04^4
P = 125000
The sum of money is $125000.
