Question

You have $90 in your bank account. each week you plan to deposit $6 from your allowance and $10 from your paycheck. The equation b=90+(10+6)w gives you the amount b in your account after w weeks from now will you have $195 in your bank account

Answer 1

Answer: After 6.5625 (or 6 1/2) weeks

Step-by-step explanation: You have to replace b with the 195.
195 = 90 + (10+6)w

Subtract 90 from both sides to get

105=(10+6)w

Simplify

105=16w

Divide both sides by 16 to get 6.5625, or 6.5
