To determine how many weeks it will take for Molly to save enough money for the boots based on the information provided, we can set up the following calculation:
Molly saves $25 each week. The cost of the boots is $150. To find out how many weeks she needs to save to reach $150, we can use the formula:
\[ \text{Number of weeks} = \frac{\text{Total cost}}{\text{Savings per week}} = \frac{150}{25} = 6 \]
So, it will take Molly 6 weeks to save enough money to buy the boots.
In terms of the graph you described, where the y-axis (vertical) goes from 0 to 160 and the x-axis (horizontal) goes from 0 to 8, you would look for the point where the line representing her savings ($25 per week) reaches $150 on the y-axis. This will occur at the 6-week mark on the x-axis.
