Maria opens a savings account with $50 and then saves $19 each work. How many weeks will it take for her account to reach $259? Represent this problem with an equation in the form px + q = r.

Options:
19x - 50 = 259
19x + 50 = 259
259 + 59 = 19x
50x + 19 = 259

Let x represent the number of weeks it will take for Maria's account to reach $259.

At the beginning, Maria has $50 in her account.
In each week, she saves $19.
The total amount in her account after x weeks would be 50 + 19x.

So, the equation that represents this problem is:
50 + 19x = 259
