Utility companies usually charge their customers based on the number of kilowatt-hours their customers consume in a period. Suppose the function A(p)=0.096p+19.50 represents the monthly charge, A, in dollars for a customer with Electric Company A consuming p kilowatt-hours of power. The function B(p)=0.104p+17.75 represents the monthly charge, B, in dollars for a customer with Electric Company B consuming p kilowatt-hours of power. Analyze the functions by interpreting the slope and y-intercept for each function in terms of the context for this situation. Then assess how the slope and y-intercept of Electric Company A compare with the slope and y-intercept of Electric Company B in this situation.(4 points)
