A regression model between sales (y in $1000), unit price (x1 in dollars), and television advertisement (x2 in dollars) resulted in the following function: = 8 - 4x1 + 5x2 For this model, SSR = 3500, SSE = 1500, and the sample size is 20.The coefficient of x2 indicates that if television advertisement is increased by $1 (holding the unit price constant), sales are expected to

A) increase by $5. B) increase by $20,000. C) increase by $5000. D) decrease by $4000. A) increase by $5. B) increase by $20,000. C) increase by $5000. D) decrease by $4000.
