Answer:
The total money that retailer receive in the end if customer used a coupon is $700 .
Explanation:
Given as :
The full price of the item that customer bought from retailer = $850
The amount of discount coupon that customer used = $150
Let the total money that retailer receive in the end = $x
Now, According to question
The total money that retailer receive in the end = The full price of the item - The amount of discount coupon
I,e $x = $850 - $150
Or, x = $700
So, the total money that retailer receive in the end = x = $700
Hence, the total money that retailer receive in the end if customer used a coupon is $700 . Answer
