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, $A = P+I=800 + 40=840$.
