Final answer:
A retail store in a mall that pays a base rent each month and a variable payment based on sales is most likely a lease agreement.
Step-by-step explanation:
The retail store in a mall that pays a base rent each month and a variable payment based on sales is most likely a lease agreement. A lease agreement is a contract between a landlord (the mall) and a tenant (the retail store) that specifies the terms of renting the space. The base rent is a fixed cost that stays the same each month, while the variable payment based on sales is a cost that fluctuates depending on the store's performance.
