8. During snowstorms, the city sends out trucks to plow. The amount of snowfall and the number of trucks sent out are shown in the table. PART A Is the relationship between the amount of snowfall and the number of trucks proportional? Explain. \( \square \) PART B For a 23 -inch snowfall, how many trucks would the city send out? Explain.

The relationship between the amount of snowfall and the number of trucks sent out is not proportional because the amount of snow does not consistently lead to a predictable number of trucks. For example, if the data shows that a 10-inch snowfall results in 5 trucks, but a 20-inch snowfall results in 10 trucks, the ratio of trucks to snow is not constant throughout the snowfall amounts, indicating that other factors influence the decision. To estimate how many trucks the city would send out for a 23-inch snowfall, we can look at the pattern in the existing data. If we extrapolate from the previous snowfall amounts, such as using interpolation or fitting a linear model based on the trucks already dispatched for specific amounts, we might predict that approximately 12 or 13 trucks could be necessary for 23 inches. However, we must consider variables such as truck availability or severity of conditions, which could affect the actual number.
