Tricky....Math..For all real numbers b and c such that the product of c and 3 is b, which of the following....
c*3 = b


=%26gt; c= b/3


=%26gt; c+3 = b/3 + 3





=%26gt; your answer is e
Reply:The produce of c and 3 is b. Product means multiply, so:





c x 3 = b





divide both sides by 3:





c = b / 3





sum of c and 3 is c + 3





You know that c = b/3, so substitute:





c + 3 = (b/3) + 3





Answer E!
