Solve the problem.At a local grocery store the demand for ground beef is approximately 50 pounds per week when the price per pound is $4, but is only 40 pounds per week when the price rises to $5.50 per pound. Assuming a linear relationship between the demand x and the price per pound p, express the price as a function of demand. Use this model to predict the demand if the price rises to $5.80 per pound.
A. p = 0.15x + 11.5; 38 pounds B. p = 11.5x + -0.15; 40 pounds C. p = - 0.15x + 11.5; 38 pounds D. p = - 0.15x - 11.5; 40 pounds
