Answer :
Sports City: If an item is 15% off, you actually pay 85%. So $180 * .85= $153
Tennis World: If an item is 20% off, you actually pay 80%. So $200 * .80= $160
Even though Tennis World had a higher percentage discount, with their price being higher to begin with the discount did not bring the price down enough so that it was a better buy that from Sports City.
** Note on my math: By doing the calculation this way, if you don't have to tell what the amount of discount is, you only have to do one step.
