The answer to your question is: 20 hours.

Step-by-step explanation:

Data

Hortencia = $350

Alex $18 / h

# hours Alex must paint to make more money than Hortencia = ?

Process

Equation                      18 x n > 350

                                     n > 350 / 18

                                     n > 19.4 hours

If Alex work 19.4 hours, he will make the same amount of money than Hortencia, then He needs to work 20 hours.

hope this !
