Answer
Explanation:
Step1: Identify car - loan amounts
The car - loan amounts for March, April, and May are all $140.00.
Step2: Calculate the average
Since the values are the same for the three - month period, the average is the same as the individual value. The formula for the average (arithmetic mean) of a set of numbers $x_1,x_2,\cdots,x_n$ is $\bar{x}=\frac{x_1 + x_2+\cdots+x_n}{n}$. Here, $x_1 = 140$, $x_2 = 140$, $x_3 = 140$, and $n = 3$. So, $\bar{x}=\frac{140 + 140+140}{3}=\frac{420}{3}=140$.
Answer:
$140.00$
