Nostrana [21]

Answer:

The amount of money due to Beth-Ann at the end of this period is $27, 300.

Step-by-step explanation:

The amount at the end of a period, when simple interest is being charged is:

Amount (A) = Principal (P) + Interest (I)

Here interest is computed using the formula:

$I=P\times R\times T$

It is provided that:

P = 24,000

R = 11%

T = 15 months = 1.25 years

Compute the Interest as follows:

$I=P\times R\times T$

$=24000\times 0.11\times 1.25\\=3300$

The interest earned is, <em>I</em> = $3,300.

Compute the amount of money due to Beth-Ann at the end of this period as follows:

$A=P+I$

$=24000+3300\\=27300$

Thus, the amount of money due to Beth-Ann at the end of this period is $27, 300.
