ive years have passed and Jamie Lee, 34 , is considering taking the plunge--not only is she engaged to be married, but she is also leciding on whether to purchase a new home. Jamie Lee's cupcake caf is a success! It has been open for over a year now and has earned itself rave reviews in the local press and from its regular customers who just cannot get enough of her delicious varieties of cupcakes. One such customer, who stopped by on a whim in the caf's first week of business, is Ross. After a whirlwind courtship, Ross, a self-employed web designer, proposed, and Jamie Lee agreed to be his wife. The bungalow that Jamie Lee has been renting for the past five years is too small for the soon-to-be newlyweds, so Jamie Lee and Ross have purchased a brand new three-bedroom, 21/2 bath home in a quiet neighborhood for $280,000. Use the provided information and the table below to calculate the affordable mortgage amount that would be suggested by a lending institution based on Jamie Lee and Ross's income. You will need to make note of the purchase price (above) of their home for future questions.
