Over the past 6 months Heads-Up Hair Care, Inc., has normally had sales of 500 bottles of A-6 Hair Conditioner per week. On the weeks when Heads-Up ran sales on its B-8 Hair Conditioner, cutting the price of B-8 from $10 to $8, sales of A-6 declined to 300 bottles.
If the price of B-8 were increased to $12, what effect would you expect this to have on the quantity demanded of A-6?
