To find out how many weeks it will take Miley to save enough money for the boots costing $150, we can calculate:
Miley saves $25 each week.
We can set up the equation to find out how many weeks (let's call it \( w \)) it will take for her to save $150:
\[ 25w = 150 \]
Now, we can solve for \( w \):
\[ w = \frac{150}{25} = 6 \]
So it will take Miley 6 weeks to save enough money to buy the boots.
