Several years ago, the flat roof over my kitchen was leaking. My friend at the hardware store told me of a new product that would fix my roof. Each can of roof sealant would cover 100 square feet and cost $23. My roof was 24 feet 8 inches long and 14 feet 6 inches wide. How many cans of roof sealant did I need to buy? (Round your answer up to the nearest whole number.)
