What is the reason for the fourth statement in this proof?
a. definition of collinear points
b. segment addition
c. subtraction property of equality
d. substitution property of equality

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
