*7. Habitat for Humanity is a wonderful charity organization that builds homes for needy families using volunteer labor. An eligible family can chose from three home sizes: 1000, 1100, and 1200 ftz. Each size house requires a certain number of labor volunteers. The Fayetteville chapter has received five applications for the upcoming 6 months. The committee in charge assigns a score to each application based on several factors. A higher score signifies more need. For the next 6 months, the Fayetteville chapter can count on a maximum of 23 volunteers. The following data summarize the scores for the applications and the required number of volunteers.
