A loss of $500 in the stock market is worse than a gain of $200 in the stock market.
kogti [31]

Answer:

-500 < 200

Step-by-step explanation:

In inequality,

less than = <

greater than = >

Less than equal to = ≤

Greater than equal to = ≥,

Here, the given sentence is,

loss of $500 is worse than a gain of $200

Generally loss represents by an amount with negative sign,

That is, loss of $ 500 = - $ 500

Also, worse than is equivalent to less than

Thus, the required inequality would be,

-500 less than 200

⇒ -500 < 200
