Which best states the central idea of the following passage Many teenagers often mow lawns, shovel snow, or babysit to make extra
money. But there's one very fun and highly profitable business that young folks
should look into: dog walking. According to a recent study in Business Life
magazine, over 40 percent of dog owners rely on someone else to walk their pet,
and 80 percent of those people would be open to trusting the right teen to do the
job. One 13-year-old who's found success in this industry is Tim Bobo, who "walks
five dogs five times a week, which scores me nearly $100." Tindalso notes that he
may have spread himself a little thin, as his schooling and other activities have
suffered a bit. But that just goes to show that there's plenty of work to go around!
If you're a teen who loves dogs, and you're looking to make a little extra money,
dog walking is certainly worth a look.
