Lerok [7]

Answer:

$14,030.48

Step-by-step explanation:

We can use the following formula to solve:

A=P(1-r)^t

<em>P = principal value </em>

<em>r = rate (decimal) </em>

<em>t = time (years)</em>

<em />

First, lets change 7.3% into a decimal:

7.3% -> \frac{7.3}{100} -> 0.073

Next, plug in the values:

A=19,000(1-0.073)^4

A=14,030.48

The value will be $14,030.48
