The answer is -20.

Now if we added 1+-20 would be -19. We would need exactly 20+-20 to get out of the negitives.

A company claims that its new bottle holds 25% more laundry soap. If their original container held 53 fluid ounces of soap, how much does the new container hold?
PLEASE HELP!

Answers

Answer:

66.25 ounces of soup

Step-by-step explanation:  

The  new container will contain 53 + 13.25 = 66.25 ounces of soap.

Hope that helps!

The new container hold 66.25 ounces.

Let x represent the capacity of the new container.

Since the new bottle holds 25% more laundry soap and the original container held 53 fluid ounces of soap, hence:

Additional space for the new container = 25% * 53 fluid ounces = 13.25 ounces

Hence:

New container capacity = 13.25 ounces + 53 ounce = 66.25 ounces

Hence the new container hold 66.25 ounces.
