Alyssa has two summer jobs: camp counselor with a community organization and babysitting her neighbor’s daughter. He earns $15 per hour as a counselor and $10 per hour babysitting. Because of her age, Alyssa can work no more than 40 hours each week, and she hopes to earn at least $450 each week.

Using c for the number of hours Alyssa works as a camp counselor and b for the number of hours she babysits, write two inequalities to represent the number of hours she can work and the amount of money she can earn.
