Answer:

The correct answer is that Charlie made a guess with a 5.2% error.

Step-by-step explanation:

We have that a % error could be written as

\% error=\frac{|approx-exact|}{exact}*100

where <em>approx is the estimate value that Charlie made, exact is the actual weight of the dog, and approx minus exact should be expressed in absolute value</em>.

<u>Doing this calculation</u>, we have that

\% error=\frac{|32.7-34.5|}{34.5}*100=\frac{120}{23}=5.22

and taking <u>the result to the nearest tenth of a percent</u>, we actually have the correct answer, wich is 5.2%.
