Mildred makes $3 an hour babysitting and $6 an hour when she works at Wendys. Her parents do not want her working more than 20 hours per week. Mildred would like to earn at least $70 a week. Write a system of inequalities that show the number of hours she could work at each job. Graph the system. Write at least four possible solutions. THANK YOU

hrs at Wendy's  x
hrs babysitting  20x
6x + 3(20x) ≥ 70
solve for x, the rest is easy
