Jill always buys the same kind of shampoo in an 11.5-ounce bottle. She is at the store buying more and sees that the bottle is now bigger and has 20% more for the same price. How many ounces of shampoo are in the new bottle?

To calculate how many ounces of shampoo are in the new bottle, multiply the amount of the previous shampoo by the 20 percent of the amount of the previous shampoo then add the product by the amount of the previous shampoo. Since the amount of the previous shampoo is 11.5-ounce bottle, the equation can be written as 11.5ounce+ 20%(11.5ounce)= total ounce of the new shampoo bottle.
> 11.5ounce+ 20%(11.5ounce)=?
> 11.5ounce+ 2.3ounce=?
> 13.8 ounces.
The total amount of the new shampoo bottle is 13.8 ounces.
