To determine which situation matches the expression, let's analyze the format typically associated with the expression. Usually, the expression likely involves addition or subtraction of fractions.
Let's break down each option:
A. Mrs. Carter's butter:
- She has a certain amount and uses a portion of it. This situation implies a subtraction scenario.
B. Tony mowing the lawn:
- He takes a total time, and the expression suggests calculating how much time remains. This involves subtraction as well.
C. Susan's orange juice:
- Susan has a certain amount and pours some into a jar. This situation also implies a subtraction scenario.
D. Chris biking:
- He bikes for a certain amount of time and then adds more time after resting. This is a straightforward addition scenario.
From these analyses, we can see:
- A, B, and C involve the concept of using or taking away from an amount (subtraction).
- D involves adding two segments of time (addition).
If the expression involves addition (e.g., finding a total), then D would be the matching situation. If the expression involves subtraction, then it could be A, B, or C, depending on the specific values given.
However, since we are looking for a scenario that adds two quantities together, the best match is:
D. Chris bikes for of an hour. He stops for a rest and then bikes for another of an hour. How many hours did Chris bike in all?
