Question

For `9x+25=88`, Deena wrote the situation "I bought some shirts at the store for 9$ each and received a $25 discount. My total bill was $88. How many shirts did I buy?" What was Deena's mistake?

Answer 1

The correct expression, so that `x` represents the number of shirts, is `9x - 25 = 88`

Explanation:

`25` is a discount, meaning that it is subtracted from the actual cost of nine shirts to arrive at the total bill of `88`.
