Luna works in a supermarket for x hours a week after school at a job that pay $4 an hour.She accepted a job that pays $8 an hour as a fast food cashier working y hours a week. She will work both jobs.She is able to work no more than 15 hours a week.Luna wants 80 dollars a week with both job combinations .Write a system of inequalities to represent the situation.
