By Anne-Marie Walker. Corn, Zea mays, belongs to the Poaceae family, and while eaten sometimes as a vegetable and sometimes as a grain, it is actually classified by botanists as a fruit, as are tomatoes, green peppers, cucumbers, zucchini and other squashes.
A garage door will cost anywhere from $200 for single doors to $4,000 for two or more doors, with better materials accounting for the higher cost. Most homeowners report spending about $1,063 for the door and installation.
There are three different types of garage door openers: chain-drive, belt-drive and screw-drive openers. Chain-drive openers are generally a good value for the price, but they are quite noisy. Prices for chain-drive openers average between $150 and $200, not including installation (which can average between $150 and $300).
