Final answer:
If a customer bought an item with a full price of $775 from a retailer and used a $125 coupon, the retailer will receive $650 in total.
Step-by-step explanation:
The customer bought an item with a full price of $775. If the customer used a coupon for $125, then the retailer will receive the remaining amount after the discount. To calculate this, subtract the coupon amount from the full price: $775 - $125 = $650. Therefore, the retailer will receive $650 in total.
