You can put this solution on YOUR website!
It follows the eqn: x%5E2-3x-28=0
in real life situation, you can represent x= money
So in %28x%2B4%29%28x-7%29=0, x has two representations:
x=-4, expenses per day in $ (money going OUT of you pocket)
x=7, rate per day(work) in $ (money coming IN your pocket)
See graph, line for expenses is going up, likewise money coming in goes up.

Thank you,
