Marjorie bought 24 bottles of juice. Each day she opens and drinks 2 of these bottles of juice. Which of the following best represents the number of unopened bottles of juice Marjorie has at the end of d days?
The number of unopened bottles of juice at the end of d days can be represented by 24 - 2d. This is because Marjorie opens and drinks 2 bottles of juice each day, so after d days she will have opened and drank 2d bottles of juice. Therefore, the number of unopened bottles will be the total number of bottles (24) minus the number of bottles she opened and drank (2d).
