The correct answer is $3409
Explanation:
The average refers to the number or value that represents the "mean" or "middle point" in two or more values. Moreover, the general rule to find this value is to add all the values, in this case, it is necessary to add the expenses of the three months, and then divide the total by 3 (number of values) as there are three months. The process is shown below:
$3260 + $3537 + $3430 = $10227
10227 ÷ 3 = 3409
