Alva estimates her expenditures for recreation as follows: May, $86;
June, $127; July, $273. What is her estimated average monthly
expense for recreation?
To find the average monthly expense, we need to add up the total expenditures and divide by the number of months:
Average monthly expense = (86 + 127 + 273) / 3
Average monthly expense = 486 / 3
Average monthly expense = $162
Therefore, Alva's estimated average monthly expense for recreation is $162.
