you solve this by using this formula
7.75x + 153.95 + 7.75y + 129.02
so first you add what you can. In this case its 153.95 and 129.02
153.95 + 129.02 = 282.97
so we get
7.75x +282.97 + 7.75y
then you try to simplify the equation more
7.75x +282.97 + 7.75y
7.75(xy) + 282.97
your answer is 7.75(xy) + 282.97
This is your answer because no matter what number x and y are you still have to multiply them by 7.75.
