Answer:

[tex]C = 82[/tex]

Step-by-step explanation:

Given

[tex]R = 5\%[/tex] -- Rate

[tex]P = 800[/tex] -- Principal

[tex]N = 2[/tex] -- Time

Required

Determine the compound interest

First, we calculate the Amount (A)

[tex]A = P(1 + R)^N[/tex]

[tex]A = 800*(1 + 5\%)^2[/tex]

Express % as decimal

[tex]A = 800*(1 + 0.05)^2[/tex]

[tex]A = 800*(1.05)^2[/tex]

[tex]A = 882[/tex]

The compound interest (C) is then calculated as:

[tex]C = A -P[/tex] i.e. Amount - Principal

[tex]C = 882 - 800[/tex]

[tex]C = 82[/tex]
