For what value(s) of x does the graph of g(x) = x+10/x^3+5x^2-50x have a hole?

The answer is c because you turn 17.5% into a decimal which gives you .175 then you times that by $361.35 which gives you 63.23625 but then you round that which gives you 63.24. then you at 63.24 pulse 361.35 and you round it which gives you $425
