scoundrel [369]
<h3>After 6 weeks from now you will have $190 in your bank account</h3>

<em><u>Solution:</u></em>

Given that,

You have ​$55 in your bank account

Each week you deposit $8 from your allowance and $15 from your paycheck

<em><u>The equation that gives the amount b in your account after w weeks is:</u></em>

b = 55 + (15 + 8)w

<em><u>How many weeks from now will you have $190 in your bank account ?</u></em>

b = 190

w = ?

Therefore,

190 = 55 + (15 + 8) w

190 = 55 + 23w

23w = 190 - 55

23w = 135

Divide both sides by 23

w = 5.869 \approx 6

Thus after 6 weeks from now you will have $190 in your bank account
