Barney Taylor is a representative for an oil refinery. He travels throughout the western United States. His total monthly expenses for August and September were $1,759.11 and $5,444.70. What was his average monthly expenditure?

Add the totals for the two months, then divide the total by 2 because that's how many months you are trying to figure out the average monthly expenditure for.

$1,759.11+$5,444.70=$7,303.81

$7,303.81/2=$3,601.905

Round $3,601.905 to 3,601.91
