To find the number of weeks it will take for Maria's account to reach $259, we can represent this problem with an equation.
Let's break down the problem:
Maria opens a savings account with $50. This initial amount is added to the total amount she saves each week, which is $19.
Let's represent the weeks as 'w'. So, after each week, the total amount in Maria's account will be:
$50 + $19w
Now, we can set up an equation to represent the problem:
$50 + $19w = $259
In this equation, 'w' represents the number of weeks and $50 represents the initial amount in the account. $19w represents the additional amount Maria saves each week, and $259 represents the target amount she wants to reach.
Now, we can solve this equation to find the value of 'w', which represents the number of weeks it will take for Maria's account to reach $259.
