Helllllllllllllllp!!!

Answer:
5 games
Step-by-step explanation:
The stems are the tens place, and the leaves are the ones.
so the first row would be for example 44, and 47.
If you need numbers that are at least 70, you count the numbers greater than or equal to 70; so anything 70 or above.
An easy way to count the numbers is to find the 7 in the stems and count all the leaves that are 0 in the 7 stem, and count all the leaves after that.
*The reason there is an 8 stem is because you don't skip any numbers in a stem and leaf plot.
There are 4 in the 7 stem, none in the 8 stem, and 1 in the 9 stem.
4+0+1=5
