Sorry i can't upload the answers but this how i did it
-Add 5, 6 and 7 together to give the total number of unit which is 18
-Then, they say 'divide equally' and so you take 18 and divide by 3 which will give you 6
-After that, they say that A will have 5 dollars more if they were split equally and so you take the amount of unit that A has which is 5 and minus away the amount of unit if it is divided equally which is 6.It would look like this(6x-5x=x)
From there you know that x=5 and so take 5 and multiply it by 18 which will give you 90 dollars which would be your answer.
