Answer:
Total number of campers = 513
Explanations:
The number of boy campers = 278
There are 43 fewer girl campers than boy campers
Number of girl campers = 278 - 43
Number of girl campers = 235
Total number of campers = Number of boy campers + Number of girl campers
Total number of campers = 278 + 235
Total number of campers = 513
