Explanation:

Step1: Understand dependent variable

A dependent variable depends on another variable. Here, the number of flower arrangements made depends on the number of hours worked. So, the number of flower arrangements made is the dependent variable.

Step2: Understand domain

The domain of a function is the set of all possible input values. In this context, the input is the number of hours worked. Since she works between 10 and 20 hours per week, the domain is working 10 - 20 hours per week.

Answer:

• Dependent variable: NUMBER OF FLOWER ARRANGEMENTS MADE
• Reasonable domain: Working 10 - 20 hours per week
