Answer

Answer:

Store A

Explanation:

Step1: Calculate price at Store A

The discount at Store A is $1200\times 0.1 = 120$. The price after discount is $1200 - 120=1080$.

Step2: Calculate price at Store B

The price after using the $100 - off$ coupon at Store B is $1200 - 100 = 1100$.

Step3: Calculate price at Store C

The price after using the $75 - off$ coupon at Store C is $1200 - 75=1125$.

Step4: Calculate price at Store D

The price after the $150$ rebate at Store D is $1200 - 150 = 1050$. Since $1050$ (Store D) < $1080$ (Store A) < $1100$ (Store B) < $1125$ (Store C), Store A offers the best deal considering the final - paid price.
