They made a decision to open a cookie store that featured bear-size cookies. Mr. V and Mr. S decorated the cookies and Mr. L sold the cookies. Mr. V could decorate a cookie in 7 minutes, Mr. S could decorate a cookie in 12 minutes. But Mr. L was eating a cookie every 9 minutes. If these teachers open the store and have no cookies decorated, how long will it take them to produce 500 decorated cookies that can be sold?<BR>\n" );
