Final answer:
Sherry can include a maximum of 20 dashboard components on a Salesforce dashboard, even if she has more reports. She'll have to prioritize or create multiple dashboards.
Step-by-step explanation:
Sherry Lara can include up to 20 dashboard components on a single Salesforce dashboard for her marketing team. This maximum limit is set by Salesforce, regardless of how many reports Sherry has.
If she has 27 reports, she will have to choose which ones are most critical to display or possibly create more than one dashboard to accommodate all the required reports. Note that each report chart equates to one dashboard component. Therefore, to maximize visibility, combining related reports or using dashboard filters could be an efficient way to provide more information within the limitation of components.
