“Calvin earns $1 for every hour he spends reading. He earns $5 for every hour of yard work that he does for his mom. If Calvin needs to earn at least $30 for his next Wild
Kratts toy, and he doesn’t want to read and do yard work (combined) for more than 7
hours per week, write a system of inequalities to represent Calvin’s situation. Don’t
forget to define your variables.”
