Paula needs to replace the floor in her family room since her cat peed in several places. She wants to put down both vinyl flooring and carpet in the room. The carpet she selected costs $2 per square foot. The vinyl floor covering costs $1 per square foot. She has $500 to spend on material and must cover an area of 300 square feet.
