The 30 members of a choir are trying to raise at least $1,500 to cover travel costs to a singing camp. they already have $600. which inequality could you solve to find the average amounts each member can raise in order to meet the goal?

The choir members need $1500, but they have $600.  Therefore, they need $1500-$600=$900 more.

Call a the average amount raised by a member.  We see that 30a >= $900.  Dividing by 30, we find that a >= $30, so the average member must raise at least $30.
