so, is just that product, recall to use "<span>3.1416 as the value of π".</span>
So for this problem, let us use x as the cost before Chet would apply a $25 gift certificate. Based on the problem, we can see that the original cost of the product cannot be more than 75 which means that it can be equal to 75 or less than 75. We can actually express the inequality as x< or = 75 since we are looking for the cost before Chet applied the $25 gift certificate. This means that we do not need to add in the 25 yet since the question asks for the cost before the application of the discount.
You can do 15-5=10 and then you have 3 left to subtract. Which means 10-3=7
Is there any choices .......
I don't think anyone can solve this without seeing the table mentioned in the question :)
