Answer: he would give away 720 hot dogs.
Step-by-step explanation:
The manager of a can cession, Stan guess that he needs 3 hot dogs for every 5 people who attended the baseball game. This means that for every 10 people that attended the baseball game, he would need
3/5 × 10 = 6 hot dogs and for every 15 people that attended the baseball game, he would need
3/5 × 15 = 9 hot dogs.
Therefore, if 1200 kids show up at the baseball game, the number of hot dogs that he would give away is
3/5 × 1200 = 720 hot dogs
