Hence the option 4 is the correct option.
Given information-
Mason opens a savings account by making a $165.85.
The money deposit by Mason every week is $20.50.
<h3>Algebraic expression-</h3>
Algebraic expression is the expression which consists the unknown variables, constant and coefficients of variables.
The algebraic expressions use to represent the set of condition of a problem in a mathematical way.
As the initial amount deposit by Mason is $165.85. Thus this amount is fixed and not going to change with the further deposit.
The money deposit by Mason every week is $20.50. This money is not fixed and increased by $20.50 every week. Thus this is a variable amount.
Therefore the algebraic expression for the given condition can be given as,
Thus the expression that shows the amount of money that will be in the account <em>x</em><em> </em>weeks after Mason opens it is,
Hence the option 4 is the correct option.
