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.
