Answer

Answer:

Take 10% off, then subtract $100.

Explanation:

Step1: Calculate price after 10% off

The price after 10% off the original price of $900 is $900\times(1 - 0.1)=900\times0.9 = 810$.

Step2: Subtract gift - card value

After subtracting the $100 gift - card from the price after discount ($810), the final price is $810-100 = 710$. If we subtract the $100 first, the price before the 10% off is $900 - 100=800$, and then 10% off gives $800\times(1 - 0.1)=720$. So taking 10% off first and then subtracting the gift - card gives a lower price.
