2. Given the following coefficients for a peak-hour shopping-trip generation model: Number of peak-hour vehicle-based shopping trips per household = 0.30 +0.20 (household size) +0.03 (annual household income in thousands of dollars) - 0.15 (employment in the household's neighborhood in hundreds) a. For a household with five members, an annual income of $98,000, and in a neighborhood with an employment of 240, predict the total number of peak-hour shopping trips generated. b. Everything else held constant, by what percentage should the household's income be decreased in order to have the number of peak-hour shopping trip equal to 1.99
