Common area maintenance (CAM) charges for retail leases in a shopping mall must be calculated. The retail mall consists of a total area of 2.8 million square feet, of which 700,000 square feet has been leased to anchor tenants that have agreed to pay $2 per rentable square foot in CAM charges. In-line tenants occupy 1.3 million square feet, and the remainder is common area, which the landlord believes will require $9 per square foot to maintain and operate each year. If the owner wants to cover the total CAM charges, how much per sq.ft will in-line tenants have to pay? Please type your answer in the box below and round it up to two decimals.
