The formula to calculate the Total Cost (TC) of Installing Impact Windows is:
\[ TC = (N \times C) + I + L \]
Where:
An impact window is a specialized type of window designed to withstand extreme weather conditions such as hurricanes and tropical storms. These windows are made from impact-resistant glass, which typically consists of two layers of tempered glass bonded with a layer of polyvinyl butyral (PVB). This construction enables the window to resist high winds and flying debris, and even if the glass breaks, the PVB layer keeps the pieces together, preventing them from causing injury or further damage. Impact windows are commonly installed in coastal areas prone to severe weather.
Let's consider an example:
Using the formula to calculate Total Cost (TC):
\[ TC = (10 \times 500) + 200 + 1000 = 5000 + 200 + 1000 = 6200 \, \text{\$} \]
This means that the total cost of installing 10 impact windows would be $6,200.
