Answer:

$38.30

Step-by-step explanation:

Mean is a measure of central tendency. It is the average of a set of numbers. It is determined by adding the numbers together and dividing it by the total number

Mean = sum of the numbers / total number

Sum of the numbers = $20 + $45 + $30.50 + $46 + $50 = $191.50

Total number = 5

Mean = $191.50 / 5 = $38.30
