Final answer:
The company offers 8 upgrade options that can be combined in different ways to provide 256 unique variations of their new homes, using the mathematical principle that 2 raised to the power of 8 equals 256.
Step-by-step explanation:
The question relates to the number of possible combinations that can be made with a set number of options. If each new home is available in 256 different variations and we assume that each upgrade option is a binary choice (e.g., chosen or not chosen), we can use the formula 2^n to find the number of upgrade options (where n is the number of options and 2 represents the binary choices).
To find the number of upgrade options needed to create 256 variations, we would solve the equation 2^n = 256. We know that 2 to the power of 8 equals 256 (since 2^8 = 256), so the company must offer 8 upgrade options.
