\(4\)  ounce bottle of glue costs  \($2.35\) .  Then...

 

\(\frac44\)  ounce bottle of glue costs  \(\frac{$2.35}{4}\) .

 

\(1\)  ounce bottle of glue costs  \($0.59\) .

 

The price per ounce is  $0.59 .

Think about this Splatmaster,

 

A pack of  9  sweatshirts cost  $88.77 .

 

How much would it cost to buy a pack of  18  sweatshirts?

It would cost twice as much, right?

 

A pack of  9 * 2  sweatshirts costs  $88.77 * 2 .

 

So..likewise...

 

A pack of  9 / 9  sweatshirts costs  $88.77 / 9

A pack of    1     sweatshirts costs        ...  ?         Can you finish it?

 

The price of  1  sweatshirt is the unit price.   smiley
