where QF is the number of jars of picante sauce sold per month, PF is the price of picante sauce, PN is the price of a bag of nacho chips, PQ is the price of a jar of queso dip, and M is consumer income. In the market served by Border Snacks, income is currently $16,000. The following regression results were obtained using 22 monthly observations:

b. If Border Snacks Inc. sets the price of picante at $6 per jar, the price of its nacho chips at $3 per bag, and the price of its queso dip at $8 per jar, what is the predicted sales of picante sauce?

c. At the prices set in part b above, what is the price elasticity of demand for picante sauce?
