Today, Isaac needs to walk his dog, water the garden, and feed his fish. DDD is the number of minutes it takes to walk his dog,

GGG is the number of minutes it takes to water the garden, and FFF is the number of minutes it takes to feed his fish.
The expression G+(D+F)G+(D+F)G, plus, left parenthesis, D, plus, F, right parenthesis describes the total number of minutes it takes Isaac to do all three tasks. We can also use the expression (G+D)+F(G+D)+Fleft parenthesis, G, plus, D, right parenthesis, plus, F to represent the same quantity.

Match each amount in the situation with the expression that represents it.

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.
