Given:

Rate of interest = 5%

Amount = $10

Time = 1 year.

To find:

The present value (initial value).

Solution:

Let x be the initial value.

Rate of interest = 5%

So, amount after 1 years is

Amount = Initial value + 5% of initial value

[tex]A=x+\dfrac{5}{100}x[/tex]

[tex]10=x+0.05x[/tex]

[tex]10=1.05x[/tex]

Divide both sides by 1.05.

[tex]\dfrac{10}{1.05}=x[/tex]

[tex]9.5238095...=x[/tex]

[tex]x\approx 9.52[/tex]

Therefore, the present value is about $9.52.

Based on the amount received, the period it is received, and the interest rate, the present value is $9.52.

The present value is calculated as:

= Amount / ( ( 1 + rate) ^ number of periods)

Solving gives:

= 10 / ( 1 + 5%)¹

= 10 / 1.05

= $9.52

In conclusion, the present value is $9.52.
