Step-by-step explanation:
Given:
Maria wants to buy a phone for at least $200.
She has savings of $125.
She plans to save $10 every week.
To write an inequality for the situation.

If she saves $10 each week.
Then, in weeks she will save in dollars =
She already has savings = $125
So her total savings in weeks in dollars will be =
She wants to buy a phone for at least $200.
