The mistake she had done is she should have reversed the inequality as per the division property of inequality.

<h3>What is inequality?</h3>

A statement of an order relationship—greater than, greater than or equal to, less than, or less than or equal to—between two numbers or algebraic expressions.

The inequality is:

500 − 30x ≥ 200 −500 −500 −30x ≥ −300 x ≥ 10

Given:

Jamie had $500 in her savings account.

She wants to have at least $200 left in the account at the end of the school year.

The inequality she had done is

500 − 30x ≥ 200 −500 −500 −30x ≥ −300 x ≥ 10

But when she was dividing she should have reversed the inequality as per the division property of inequality.
