By what percent is 70 less than 200

200/x=100/70

(200/x)*x=(100/70)*x       - we multiply both sides of the equation by x

200=1.42857142857*x       - we divide both sides of the equation by                                                                                       (1.42857142857) to get x
200/1.42857142857=x
 


x=140

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
