Question

Chen has a part-time job at a bakery. The table below shows his daily earnings.Which stem-and-leaf plot correctly represents the data in the table?

Answer 1

In the steam and leaf plot, the steam represents the tens and the units, and the leaf represents the tenths of each daily earning.

Then, to represent $37.30 we have to write 37 on the steam column and 3 on the leaf column, that is, the key is 37 | 3 = $37.30

Applying this rule to the values of the table, we get:

Steam | Leaf

37 | 3

38 | 1 1 3

39 | 0 8

40 |

41 | 7 8

42 | 5 5
