Answer
Explanation:
Step1: Count values in 60s
In the stem - and - leaf plot, the stem value of 6 has 2 leaf values (2 and 3). So the number of values in the 60s is 2.
Step2: Find least value
The lowest stem value is 3, and the lowest leaf value for the stem of 3 is 0. So the least amount spent overall is 30.
Step3: Find greatest value in 50s
The stem value is 5. The greatest leaf value for the stem of 5 is 8. So the greatest amount spent in the 50s is 58.
Answer:
(a) 2 (b) 30 (c) 58
