Suppose you have $28.00 in your bank account and start saving $18.25 every week. Your friend has $161.00 in his account and is withdrawing $15 every week. When will your account balances be the same?

Set up savings and withdrawal equations where w is the number of weeks. B(w) is the current balance

• You --> B(w) = 18.25w + 28
• Your friend --> B(w) = 161 - 15w

Set them equal to each other
18.25w + 28 = 161 - 15w

Type that problem into the search engine, and you get w = 4.
