What adding equation gives you the total of 250

Well, 125+125= 250. If that was what your asking.

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

Iam not sure , but probably 750 or 7.5
