You usually buy a 16.5-ounce bottle of shampoo. there is a new bottle that says it gives you 30% more free.

Hopefully, this is your desired setup. (I noticed the formula you have to fill in there.)

Have a good day.

Step-by-step explanation:

Hi.

You could use the percent change formula.

Since we know it is a percent increase then we will do new-old instead of old-new:

x is the new amount of shampoo.

16.5 is the original amount (old) of shampoo.

The percent increase is 30%=0.30 .

So we have the following equation:

We could have found the equation like this:

Subtract 16.5 on both sides:

Divide both sides by 16.5:

By us of symmetric property of equality:

Step-by-step explanation:

First, we have to find an expression to find , then we fit the answer in the blanks.

So, the represent the new bottle, which according to the problem has 30% more ounces than the old one which has 16.5 ounces. That means:

As you can observe, the equation is adding the additional 30% ounces to the old bottle to find the new one.

If we fit this expression in the blanks, would be:

Therefore, the answer is

the circle one
