Hi Jacob;
Have you considered the two equation (then their inequalities) that have to be considered.
You know
1) x + y = 480 the money divided up
2) y = 4x as he would like to donate four times the amount to the youth fund.
If you graph these two lines then check the inequalities you can work out the shaded regions.
Dan will donate up to $480 to charity. The money will be divided between two charities: the City Youth Fund and the Educational Growth Foundation. Dan would like to donate at least
to the Educational Growth Foundation. He would also like the amount donated to the Educational Growth Foundation to be at least four times the amount donated to the City Youth Fund. Let x denote the amount of money (in dollars) donated to the City Youth Fund. Let y denote the amount of money (in dollars) donated to the Educational Growth Foundation. Shade the region corresponding to all values of x and y that satisfy these requirements.
