A real estate office handles an apartment complex with 50 units. When the rent is $380 per month, all 50 units are occupied. When the rent is$425, however, the average number of occupied units drops to 47. Assume that the relationship between the monthly rent p and the demand x is linear. (The term demand refers to the number of occupied units.)

Linear Extrapolation Predict the number of occupied units when the rent is set at $455.

Consider the operation $N: P_2 \rightarrow P_3$ that takes $p(x)$ in $P_n$ to $(x-1) p(x)$ in $P_{n+1}$. Do you think this corresponds to a linear transformation from $R^3$ to $R^4$ ? If so, what is its matrix?
