Ashley wants to wallpaper the back wall of her bedroom. The wall is in the shape of a rectangle. Its length is \(16\) feet and its width is \(13\) feet. Suppose wallpaper costs \(\$5\) for each square foot. How much will wallpaper cost for the wall.
The manufacturing cost of an air-conditioning unit $544, and the full-replacement extended warranty costs $113. If the manufacturer sells 506,970 units with extended warranties and must replace 20% of them as a result, how much will the replacement costs be? (Note: Assume manufacturing costs and replacement costs are the same.)
