49 percent of all people who buy running shoes don't run at all. Assuming 340,000 people buy running shoes, how many will use them to run in?
Answer provided by our tutors
If 49% of the people don't run at all, then the rest, 100 - 49 = 51% are using the shoes to run.
We need to find 51% of 340,000:
0.51*340000 = 173,400
173,400 people will use the soes to run.
