Answer:
Let's assume that the initial price of the refrigerator was $100.
Shop A raised the price by 15%, which means the new price was:
$100 + 15% of $100 = $115
Then, they sold it at a 15% discount, which means the final price was:
$115 - 15% of $115 = $97.75
Shop B raised the price by 10%, which means the new price was:
$100 + 10% of $100 = $110
Then, they sold it at a 10% discount, which means the final price was:
$110 - 10% of $110 = $99
Therefore, Shop A sold the refrigerator at a higher price after the price increase and discount.
