Explanation:

Step1: Recall average formula

The formula for the average (arithmetic - mean) of a set of numbers is $\text{Average}=\frac{\sum_{i = 1}^{n}x_{i}}{n}$, where $x_{i}$ are the individual values and $n$ is the number of values.

Step2: Identify values and number of values

The number of receipts per quarter are $x_1 = 80$, $x_2=60$, $x_3 = 40$, $x_4 = 50$, and $n = 4$.

Step3: Calculate the sum

$\sum_{i = 1}^{4}x_{i}=80 + 60+40 + 50=230$.

Step4: Calculate the average

$\text{Average}=\frac{230}{4}=57.5$.

Answer:

57.5
