Question

# Lawren has $1000 in a saving account. He wants to save at least $400 before winter. He withdraws $50 every week for daily requirements. Write an inequality that represents Lawren’s situation.

- 1000+50w 400
- 1000-50w 400
- 1000 + 50w400
- 1000-50w 400

Hint:

### We are given that Lawren has $1000 in a saving account. He withdraws $50 per week for daily requirements. He has to save at least $400 dollars. We have to write the inequality of the above equation.

## The correct answer is: 1000+50w 400

### Total amount in saving account is $1000.

Amount withdraw per week is $50.

The amount he has to save the least is $400.

Let the number of weeks he deduct the amount till he reached the balance of at least $400 be denoted by w.

The balance should be at least $400. So, the amount can be greater than or equal to this quantity.

Amount $400

The amount $1000 is constant.

The amount deducted till he reached the least balance is $50×w i.e. 50w. The amount is deducted, so we will subtract it from the saved amount.

The inequality will be

1000 - 50w 400

For such questions, we have to see which quantity is constant and variable. We have be careful about the words like “at least”, “at most”, etc.
