You buy 20 fluid ounces of shampoo for $4.40 or 24 fluid ounces for $4.80. Which is the better buy? P.S. Can u please show me the formula? This is a unit rate problem.

to make this easier lets convert dollars into cents so : 440 cents gives 24 , 440÷20=22 cents for each ounce
the other deal : 480÷24=20 cents for each ounce This one is cheaper per ounce this one is better
Formula for price of ounce = total Price÷Number of ounces

Just do this. I don’t know if you’re a visual learner or not but I figured this might help
