D no Solution would be the answer
It should be $10,062.50 because if you multiply 850 and 25% (turn to decimal .25) then you add 850 again and you get 10,062.50.
5x^2-45=0
<em>*Add 45 to both sides*</em>
5x^2=45
<em>*Divide both sides by 5*</em>
x^2=9
<em>*Take the square root of both sides*</em>
x=+/-9
Hope this helps!!
