The cost of equipment to apply epoxy paint to a warehouse floor is $1400. Materials and supplies (masking tape, surface repair material, solvents, cleanup supplies, etc.) will cost $2.03 per ft². Alternatively, a contractor can be hired annually to do the job for $3.25 per ft². If the cost of the equipment will be recovered at i = 10% per year over a 3 year period with no salvage value, the number of square feet that must be treated each year to justify the equipment purchase is closest to:

(a) 460 ft²

(b) 953 ft²

(c) 1148 ft²

(d) 2457 ft²
