Answer 2

Solution:

To compare the price reduction in the two stores, let's calculate the final price of the item in each store after the discounts have been applied.

1. First Store: - The price is reduced by 10% first, then by another 10%. - Let's assume the original price is $100. - After the first 10% reduction, the price becomes $100 - (10% of $100) = $100 - $10 = $90. - After the second 10% reduction, the price becomes $90 - (10% of $90) = $90 - $9 = $81.

2. Second Store: - The price is reduced by 20% directly. - Using the same original price of $100: - After the 20% reduction, the price becomes $100 - (20% of $100) = $100 - $20 = $80.

Conclusion:

The item is cheaper in the second store where the price is $80, compared to the first store where the price is $81 after the double 10% reduction.

I hope this helps! If you have any other questions, feel free to ask.
