we know that
A rate is a ratio that compares quantities in different units. A unit rate is a rate where the second quantity is one unit
so
In this problem to find the unit rate
Divide $\(5.99\) by \(13\ ounces\)
\(unit\ rate=\frac{5.99}{13}\frac{dollars}{ounce} \\ \\ unit\ rate=0.46\frac{dollars}{ounce}\)
therefore
the answer is
the unit rate is equal to \(0.46\frac{dollars}{ounce}\)
