Answer:

Step-by-step explanation:
The better option will be at DiscountsRUs 40% off on any purchase.
<h3>What is the discount?</h3>
The amount of money which is reduced on any product below its actual selling price is called the discount.
here we have two offers from the two stores Dominic had a coupon for 15 off his purchase at Save4You. At DiscountsRUs, there was a sale of 40% off on any purchase.
For a Dominic, the discount is fixed for any purchase that is if you purchase a $50 product or a $1000 product you will be getting only a $15 discount.
Now for the second store, the discount is given as 40% so if you purchase $50 your discount will be $20. If you purchase $1000 so 40% discount will be $400.
Therefore better option will be at DiscountsRUs 40% off on any purchase.
