Brianna is keeping track of how much money she saves.
She has $60 saved and saves another $15 each week.

How long will it take Brianna to save enough to buy a pair
of $180 sneakers? Show or explain your thinking.

Let’s start by setting up an equation, with x representing the amount of weeks:

15x + 60 = 180

We can subtract 60 from both sides to isolate the variable term:

15x + (60 - 60) = 180 - 60

15x = 120

120 / 15 gives us 8.

It will take Brianna 8 weeks to save enough to buy a pair of $180 sneakers.
