Answer:

A.) Denna consider wrong the discount. She added it instead of resting it

B.) 9x - 25 = 88

C.) I bought some shirts at the store for $9 each, to get that price ,  I must be a member of the club ,  the membership is one pay of 25. My total bill was $88

Step-by-step explanation:

To get the total bill we have to multiple the quantity of shirts (x)  by the price minus the discount she get.  

So, in the equation Denna consider wrong the discount,  She added it instead of resting it .  It should be

9x - 25 = 88

Where

Price =$9

x= quantity of shirts

discount = $25

Total bill= $88

To re-write the situation we have to consider another payment,  It could be a membership to a club.
