Sales Forecast Modeling. The change in the quantity of Cheez Sticks demanded in any given week is inversely proportional to the change in sales of Pretzel Q's in the previous week. That is, if sales of Pretzel Q's fell by X percent last week, sales of Cheez Sticks can be expected to rise by 2X percent this week.
A. Write the equation for next week's sales of Cheez Sticks, using the symbols C = sales of Cheez Sticks, Q = sales of Pretzel Q's, and t = time. Assume there will be no shortages of either product.
B. Last week 600 units of C and 350 units of Q were sold. Two weeks ago, 400 units of Q were sold. What would you predict the sales of C to be this week?
