Hi, Jayson,

There are a lot of ways to solve this. Let's try this.

First, consider when one calculates a discount price:

**Original price - amount of discount = discount price**

The amount of discount is how much was taken off. The discount price is what the selling price was after the discount.

Now, to calculate the amount of a discount, we would multiply the original price by the percent discount. So, for this problem:

amount of discount = **0.10x** 0.10 comes from the 10%

always move the decimal point

2 places to the left

We are taking **x = original price of the item**.

So, then, our equation becomes:

**x - 0.10x = discount price**

We are given the discount price, $97.40. So, then, we have:

**x - 0.10x = 97.40**

Solving this for x:

**0.90x = 97.40**

x = approx. **$108.22** is the discounted price.

Good luck, Jayson. I hope this helps.

Till Then,

Steve
