Question

Manuel has $600 in a savings account at the beginning of the summer. He wants to have at least $300 in the account at the end of the summer. He withdraws $28 each week for food. Which inequality represents w, the number of weeks Manuel can withdraw money while not dropping below a $300 balance?

Answer 1

Answer:

$600-28w \geq 300$

Step-by-step explanation:

Manuel has $600 in a savings account at the beginning of the summer.

He withdraws $28 each week for food.

Let w be the no. of weeks

He withdraws for food in w weeks = $28w

Amount left in the account = $600-28w$

Since we are given that He wants to have at least $300 in the account at the end of the summer.

So, inequality becomes : $600-28w \geq 300$

Hence An inequality represents w, the number of weeks Manuel can withdraw money while not dropping below a $300 balance is $600-28w \geq 300$

Answer 2

600-28(w)=300
-28(w)=-300
~approximately 10 weeks
