Answer:

D

Step-by-step explanation:

A is correct because the cost of the dinner before the tip is 100%. Add 18% to that to get 118%, which is equal to 1.18.
B is correct because if you add 1 and 0.18, you get 1.18. You multiply that by d and get the same equation as A.
C is correct because 0.18d + (1)d = 1.18d = t, and it is the same equation as A.
Therefore, D is wrong.
