The amount of rent that the lessee is required to pay the lessor will be addressed in "V. Base Rent." The first available line of this paragraph requires the lessor's monthly monetary expectation to be stated out. There is a second empty line enclosed by parenthesis and a dollar symbol. This means that there can be as many lines following as needed until all requirements are met. Generally, the base rent for commercial leases is defined as some percentage of the tenant's gross sales. So if the gross sales are $10,000 per month, then the base rent would be $100 per month ($10,000 divided by 12). If the sales decline to $8,000 per month, then the base rent would be reduced to $75 ($8,000 divided by 12). As long as the lease contains the appropriate language regarding base rent, it can be any number of things including percentages, flat fees, deductions, etc. In short, the base rent is how much the lessee has to pay the lessor each month. It may be one price for everyone who rents space from the lessee, or it could be different amounts depending on the type of business that they conduct. As long as the lease states what the base rent is, it can be whatever the parties decide it should be.
