We have been given that Mark had $436.
Further, we are given that Chris has $86 lesser than what mark had.
Let us assume that Chris has $x. Therefore, we can set up an equation:
(Amount Chris had) + $86 = (Amount Mark had)
[tex]x+86=436[/tex]
Upon subtracting 86 from both the sides, we get:
[tex]x=436-86[/tex]
Therefore, the required expression that represent the amount of money that Chris had is [tex]436-86[/tex].
