Beth estimates her expenditures for transportation as follows:
May, $91; June, $122; July $478. What is her estimated average
monthly expense for transportation?
To find the average monthly expense, we need to add up the expenses for May, June, and July and then divide by the number of months (3):
Average monthly expense = (91 + 122 + 478) / 3
Average monthly expense = 691 / 3
Average monthly expense ≈ $230.33
Therefore, Beth's estimated average monthly expense for transportation is approximately $230.33.
