The four operations are addition, subtraction, multiplication, and division.

Representing and solving word problems involves choosing the correct operation(s).

Multiplication can be used to find a total when a given amount is added multiple times.

The amount Sandy bought is 3 times the amount Randy bought.

Randy bought 2 pounds. Solve for 3 groups of 2.

Since Trina's cat weighs 5 pounds more than Gina's cat weighs, subtract 5 pounds from the weight of Trina's cat.

So, Gina's cat weighs 9 pounds.
