Answer:
34 weeks
Step-by-step explanation:
Hello!
We can set up an equation to solve for the number of weeks.
Let w = the number of weeks he is saving up.
The equation is 
- 315 is the target amount
- 115 is the current amount
- 10w is the rate of growth
- 140 is the current debt
<h3>Solve for w</h3>
He needs to save up for 34 weeks.
