Question

a veterinarian uses a line plot to record the weights of different cats throughout the day. what is the weight difference, in pounds, between the heaviest cat and the lightest cat? (a) $1\frac{1}{4}$ pounds (b) $1\frac{2}{5}$ pounds (c) $1\frac{2}{10}$ pounds (d) 2 pounds

Explanation:

Step1: Identify heaviest and lightest weights

The lightest cat weight is \(8\frac{1}{2}\) pounds and the heaviest cat weight is \(10\) pounds.

Step2: Calculate weight difference

\(10 - 8\frac{1}{2}=10-\frac{17}{2}=\frac{20 - 17}{2}=\frac{3}{2}=1\frac{1}{2}=1\frac{5}{10}\) pounds.

Answer:

C. \(1\frac{2}{10}\) pounds
