How does promotional pricing for monthly rate affect the weekly and daily rates?

Promotional pricing given is reflected in the monthly pricing on the corporate serviced apartment listing page. 

The weekly and daily promotional pricing are computed based on the percentage of the monthly promotional pricing.
