You have ​$85 in your bank account. Each week you plan to deposit ​$77 from your allowance and ​$25 from your paycheck. The equation b=85+​(25+7​)w gives the amount b in your account after w weeks. How many weeks from now will you have ​$270 in your bank​ account?

We want to solve this

 

270  =  85+​(25+7​)w     subtract  85  from both sides

 

185 =  32w         divide both sides by 32

 

w ≈ 6 weeks
