It will cost 88 tokens to park for 22 hours because you will have to multiply the 4 by the 22 to get the 88 tokens so therefore the answer is 88 tokens
Answer:
1, 2, 2, 2, 3, 8, 9
Step-by-step explanation:
The following data represent the times in minutes required for 18 co-workers to commute to work
48 42 31 29 41 22 38 38 21 39 22 48 22 12 34 32 23 28
Rewrite this data in ascending order
12 21 22 22 22 23 28 29 31 32 34 38 38 39 41 42 48 48
Now, the stem-and-leaf plot is

The second row represents the leaves for the given data points in the range 20 to 29 for this stem-and-leaf plot, so the answer is
1, 2, 2, 2, 3, 8, 9
