your local radio station is having their yearly MP3 player and concert giveaway. For one minute every 5th caller will win an MP3
player and every 7th caller. will win concert tickets. You were just the first caller to win both an MP3 player and concert tickets! What number were you?
You are the 35th caller 7x5=35, with that being 35 you cannot be the 6th because you are still going to be 1 short and 1 more. So multiply then to get your answer 35
