Answer:

9 or more

Explanation:

In order to make a profit, Trina must sell enough vases so that her revenue exceeds her costs.

Trina's cost is ...

162 + 4.25v . . . . to make v vases

Trina's revenue is ...

24.50v . . . . . . . from selling v vases

v > 8 . . . . . . . . . . divide by 20.25

Trina must sell at least 9 vases in order to make a profit.
