You have ​$85 in your bank account. Each week you plan to deposit ​$7 from your allowance and ​$15 from your paycheck. The equation b=85+​(15+7​)w gives the amount b in your account after w weeks. How many weeks from now will you have ​$210 in your bank​ account?

b=85+​(15+7​)w 

 

210 = 85 + (22)*w

210 - 85 = 22w

125 = 22w

w = 125 / 22

w = 5.68 weeks to have $210 in the bank.
