Answer:

Step-by-step explanation:

The formula for determining compound interest is expressed as

B = p(1 + r)^t

where

B is the balance (final amount),

p is the principle (starting amount),

r is the interest rate.

t is the time in years.

From the information provided,

p = $1

r = 10% = 10/100 = 0.1

t = 3 years

The balance in 3 years would be

A = 1(1 + 0.1)^3

A = 1(1.1)^3

A = $1.331

The interest earned after 3 years is

1.331 – 1 = $0.331

Rounding up to the nearest tenth, it becomes $0.3
