Answer:
Meg has (4 + d) dollars
Pat has (2m + 2d) dollars
Explanation:
Let d represents Loc's money
Let m represents Meg's money
Let p represents Pat's money
We are given that Meg has $4 more than loc
Mathematically,
m = 4 + d
Therefore, Meg has (4 + d) dollars
We are also given that Pat has twice as much as meg and loc combined
Mathematically,
p = 2*(m + d)
p = 2m + 2d
Therefore, Pat has (2m + 2d) dollars
Note: We have 2 equations and 3 unknowns therefore, we cannot have a unique solution to this problem.
