emma borrowed $9,000. the loan has a simple interest rate of 15%. if she takes 5 years to pay it back, how…

Explanation:

Step1: Identify the formula

The simple - interest formula is $I = PRT$, where $P$ is the principal amount, $R$ is the interest rate (in decimal form), and $T$ is the time in years.

Step2: Convert the interest rate to decimal

The interest rate $R = 15%=0.15$. The principal amount $P=$9000$ and the time $T = 5$ years.

Step3: Substitute values into the formula

$I=P\times R\times T=9000\times0.15\times5$.

Step4: Calculate the interest

$9000\times0.15\times5 = 9000\times0.75=$6750$.

Answer:

$6750$
