Leah Berry is entering her senior year as an accounting major and has a number of options for her summer break. Her options for the 3-month break follow:

(1) Work full time at a local accounting firm making $3,400 per month.

(2) Take a summer class which will cost $800 per month and work half time making $1,800 per month.

(3) Take two classes at a cost of $1,200 and not work at all during the summer.

Leahs incremental profit (or loss) if she chooses option 2 over option 1 would be

($1,100) per month.($2,200) per month.($2,400) per month.$1,300 per month.($2,100) per month
