Plugging in the values we have:
To find out when she has enough to purchase the bicycle, we set this equation equal to the cost of the bicycle:
This equation represents Jane's savings towards the bicycle, where
Here's how you would solve it:
- Subtract 50 from both sides:
- Divide by 15:
So, Jane needs to save for 9 weeks to afford the bicycle.
