Stem & Leaf diagram, please explain watch

1. The stem and leaf diagram is formed by splitting the numbers into two parts - in this case, tens and units.The tens form the 'stem' and the units form the 'leaves'.

This information is given to us in the Key.It is usual for the numbers to be ordered.
So, for example,
2 | 1
represents 21

or

0 | 3
represents 3

Now your questions says:"Emma worked for 12 Weeks.
The stem and leaf diagram shows the number of sales she made each week."
"Each week she could earn a bonus of £15 or £20."

N.o. of Sales | Bonus
Under 25----------£0
25 - 30-------------£15
Over 30------------£30

According to the 1st leaf, she sold 7 items. SO her bonus was £0
According to the 2nd leaf, she sold 15 items. SO her bonus was £0
According to the 3rd leaf, she sold 18 items. SO her bonus was £0
According to the 4th leaf, she sold 19 items. SO her bonus was £0
According to the 5th leaf, she sold 20 items. SO her bonus was £0
