CAM charges for retail leases in a shopping mall must be calculated. The retail mall consists of a total area of $2\mathrm{.}8$ million square feet, of which $800,000$ square feet has been leased to anchor tenants that have agreed to pay $$2$ per rentable square foot in CAM charges $($$$2**800,000).$ In$-$line tenants occupy $1\mathrm{.}3$ million square feet, and the remainder is common area, which the landlord believes will require $$8$ per square foot to maintain and operate each year. To cover the total CAM charges, how much will the owner have to charge the in$-$line tenants pay per square foot of the area they occupy, after the CAM payment by anchor tenants?
