Final answer:
The best option for Carla would be to become (option 4) self-employed as it will give her the flexibility she needs to support her children's extracurricular activities while pursuing her passion in cosmetology.
Step-by-step explanation:
The best employment strategy for Carla would be to become self-employed. Being self-employed would give Carla the flexibility she needs to drive her kids to activities and attend events. She can schedule her work around her children's activities and have control over her own hours.
Since Carla's husband has a good job and she doesn't need a steady income, she can focus on building her own client base and working on jobs that interest her. This way, she can have more control over her career and pursue her passion in cosmetology. Self-employment would offer even greater control over her schedule and possibly her business model, which means she can tailor her work-life balance to suit her family's needs.
