1. Louise McIntyre’s monthly gross income is \$2,000. Her employer withholds \$400 in federal, state, and local income taxes and \$160 in Social Security taxes per month. Louise contributes \$80 per month for her IRA. Her monthly credit payments for VISA, MasterCard, and Discover card are \$35, \$30, and \$20, respectively. Her monthly payment on an automobile loan is \$285. What is Louise’s debt payments-to-income ratio? Is Louise living within her means? Louise’s Gross Income| =| \$2,000|

Less: Income taxes| =| -400|
Less: Social Security Tax| =| -160|
