Four brands of soap are available in a local store. Compute the unit price and decide which brand is the best buy.
Brand Ounces Total Price Unit Price
Squeaky Clean 5.5 $0.36
Smell Fresh 7.5 0.41
Feel Nice 4.5 0.31
Look Bright 6.5 0.44
Compute the unit price and decide which brand is the best buy.

To find the best buy, you'll need to figure out the price per ounce (unit price).
Squeaky Clean at 5.5 ounces costs $0.36.
Divide: 0.36 / 5.5 = $0.065 per ounce
Smell Fresh: 0.41 / 7.5 = $0.055 per ounce.
I think you can finish these calculations and decide which is the best buy.
We'll be glad to check your answers. 
the best buy is Smell Fresh ar $0.054
Sure hope this is right!
