You have $22 in your bank account, and you deposit $11.50 per week. Your cousin has $218 in his bank account and is withdrawing $13 per week. The graph of this problem situation intersects at x=8. What does this mean?
In 8 weeks, you will have triple the amount of money in your account.
In 8 weeks, your cousin will run out of money.
In 8 weeks, both bank accounts will have the same amount of money in them.
In 8 weeks, you will break-even.
If the graphs intersect, their values are equal at that point.
