Final answer:
The expression to represent the total number of balls is 14(12) + 23(16).
Step-by-step explanation:
The expression to represent the total number of balls is B. Expression: 14(12) + 23(16). To find the total number of baseballs, we multiply the number of boxes of baseballs (14) by the number of baseballs in each box (12), which gives us 14(12). Similarly, to find the total number of tennis balls, we multiply the number of boxes of tennis balls (23) by the number of tennis balls in each box (16), which gives us 23(16). Then, we add the total number of baseballs to the total number of tennis balls to get the total number of balls in the camp.
