Let our two variables be:
p # of pharmacy hours
b # of babysitting hours
Then we should have two statements from the given facts:
and
We can graph these inequalities by solving for either p or b in both inequality.
Once the inequalities are graphed then any point that is shaded in their intersection will work.
