Question 974412: edith babysits for x hours a week after school at a job that pays $4 an hour. She has accepted a job that pay $8 an hour as a library assistant working y hours a week. She will work both jobs. She is able to work no more than 15 hours a week, due to school commitments. Edith wants to earn at least $80 a week working a combination of both jobs.

2) Graph these inequalities o the set of axes below (then there's a graph)
3) Determine and state one combination of hours that will allow Edith to earn at least $80 per week while working no more than 15 hours.
