Parker is planning for a school picnic. He would like to have 2 hot dogs per person and 15 extra on hand. How many hot dogs does he need if there are 116 students and 8 teachers?

There are 116 + 8 = 124 people attending. At 2 hot dogs per person, Parker needs 124 × 2 = 248 hot dogs, then he adds 15 extra: 248 + 15 = 263. The correct choice is 263 hot dogs.
