Answer

Explanation:

Step1: Calculate price if 15% discount first

The original price is $450. After applying a 15% discount, the price is $450\times(1 - 0.15)=450\times0.85 = 382.5$. Then applying the $50 - off$ coupon, the final price is $382.5-50=332.5$.

Step2: Calculate price if $50 - off$ first

First, apply the $50 - off$ coupon to the original price of $450$. The price becomes $450 - 50=400$. Then apply the 15% discount, the final price is $400\times(1 - 0.15)=400\times0.85 = 340$.

Answer:

Apply the 15% discount first, and the final purchase price is $332.50.
