ANSWER

• Mean = 24.5

,

• Median = 27.5

,

• Mode = 28

Step-by-step explanation

When we add or subtract a constant from each data in a data set, the mean, median and mode change in the same amount.

So if before we had that the mean = 21.5, median = 24.5 and mode = 25 and we add $3 to each data, then all three values change by adding 3:

• new mean, = previous mean + 3 = 21.5 + 3 =, 24.5

,

• new median, = previous median + 3 = 24.5 + 3 =, 27.5

,

• new mode, = previous mode + 3 = 25 + 3 = ,28
