Answer: Gavin will save $16.45 if he waits until next week to buy the jacket.
Explanation:
Given: Current Market price of jacket = $38.95
Sales price next week = $22.50
Amount he can save = (Current Market price of jacket)- (Sales price next week )
i.e. Amount he can save = $ (38.95-22.50)
i.e. Amount he can save = $ 16.45
Hence, Gavin will save $16.45 if he waits until next week to buy the jacket.
