29.99x-8.75x=17884
21.24x=17884
X=841 sunglasses
It actually comes out to be more than 841, but since you can’t make .9 sunglasses then you round to the lower whole number.
6x^4-17x^3-7x^2+13x=3
6x^4-17x^3-7x^2+13x-3=3-3
6x^4-17x^3-7x^2+13x-3=0
y=6x^4-17x^3-7x^2+13x-3
y=0
The solutions are: x=-1, 1/2, 1/3 and 3
