The general form is ax²+bx+c=0,
so at least we know b has to be 0. None of the values match unless we multiply everything by 4. That leads to answer B, a=1, b=0 and c=20
0 because companies A says he gets 80.000 dollars per year with a 1,000 dollars increase every year so companies B will higher have to wait 0 years to be higher than companies A
