what is the total payment required to pay off a promissory note issued for $800.00 at 10% ordinary interest and a 180 - day term? $? round to the nearest cent.
Answer
# Answer:
$840.00
# Explanation:
## Step1: Identify the simple - interest formula
$I = Prt$, where $P$ is the principal amount, $r$ is the annual interest rate, and $t$ is the time in years.
## Step2: Convert the time to years
The time $t$ is 180 days. Since there are 360 days in a year for ordinary interest, $t=\frac{180}{360}=0.5$ years.
## Step3: Identify the principal and rate
The principal $P = 800$ and the annual interest rate $r=0.10$.
## Step4: Calculate the interest
$I=Prt=800\times0.10\times0.5 = 40$.
## Step5: Calculate the total payment
The total payment $A$ is the sum of the principal and the interest, $A = P+I=800 + 40=840$.
