The first answer is correct, if you go back by 5% each year you will see that.

Answer:

$ 7,835.26

Step-by-step explanation:

Let x be the value of his money five years ago,

Given,

Annual rate of interest = 5 %,

Time = 5 years,

So, the amount after 5 years,

[tex]A=x(1+\frac{5}{100})^5[/tex]

[tex]=x(1+0.05)^5[/tex]

[tex]=x(1.05)^5[/tex]

According to the question,

[tex]x(1.05)^5=10000[/tex]

[tex]\implies x = 7835.262\approx 7835.26[/tex]

Hence, the value of his money five years ago was $ 7,835.26.
