At an art auction, Giannina's painting sold for over $300. Write an inequality that describes P, the price of Geannina's painting in dollars.

If P is the price of the painting, and the painting is over $300, the inequality is P>300

We are given : Giannina's painting sold for over $300.

Let the price of Geannina's painting in dollars = P.

Note: We are given a word " over " in above statement.

Over word represents more than. So, we need to use more than inequality symbol to write an inequality for the given statement.

Let us rephrase the given statement.

" Price P is greater than $300".

Now, we can write an inequality:

P> 300.

Therefore, the required inequality for given statement is P > 300.
