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?

To find 49% of 340,000 people that don't run at all, multiply 0.49 with 340,000 to get 166,600. To find out who do run in them, subtract 166,000 from 340,000 to get 173,400 which is the number of people who bought and use the running shoes. Hope this helps and mark as brainliest!
