Interpreting linear expressions

Today, Isaac needs to walk his dog, water the garden, and feed his fish. He wants to find the total amount of time these things will take. $D$ is the amount of time it takes to walk his dog, $G$ is the amount of time it takes to water the garden, and $F$ is the amount of time it takes to feed his fish. There are different ways of thinking about how to add the three times. **Match the expressions to the corresponding descriptions of how to add the times.** For reference: The dog is an animal, and he needs to go outside to walk. The garden is a bunch of plants (not an animal), and it is outside. The fish is an animal, and she lives in a water tank inside. [[☃ categorizer 1]]
