Answer:
4 bags
Explanation:
The way to read a step and leaf diagram is to consider the "stem" as the tens digit and "leaf" ans the ones digit.
So "0" in stem and "5" in leaf would be the number "05" or simply "5"
Also, "2" in stem and "4" in leaf would be the number "24"
When we have more numbers in leaf, they are basically different numbers. So lets list the numbers from stem-and-leaf plot:
5, 24, 30, 34, 65, 70, 74, 87, 90
The question asks for how many numbers are there LESS THAN 40?
the numbers less than 40 are:
5, 24, 30, 34
That is 4 numbers
