#### Answer

See below for answers and explanations.

#### Work Step by Step

a. Using the graph given in the exercise, we have $\lim_{x\to3^-}f(x)=0.93$ b. We have $\lim_{x\to3^+}f(x)=1.15$ c. Since $\lim_{x\to3^-}f(x)\ne \lim_{x\to3^+}f(x)$, $\lim_{x\to3}f(x)$ does not exist and it is shown by the graph with a gap at $x=3$. d. The price jumps vertically at each integer weight in ounces, and it is possibly due to the increasing cost in transportation.
