A. 3.75x
B. 3.4x
C. 3.25x
D. 3x + .25
E. 0.55x



Work backwards.

300% of x is going to be 100% of x multiplied by 3. So 300% of x = 3x
25% more than 300% of x is also the same as saying find 25% of 3x and add it to 3x
So we get 3x*1/4 = 3x/4 = 0.75x
0.75x + 3x = 3.75x

We can create the expression:

1.25(3x) = 3.75x

Answer: A

125% of 300% of x

= 1.25*3x

= 3.75x , answer will be (A)
