The manager of a summer camp has 14 baseballs and 23 tennis balls. The manager buys some boxes of baseballs with 12 baseballs to a box and a equal number of boxes of tennis balls with 16 tennis balls to a box. Write an expression to represent the total number of balls

To set up an equation correctly, it is important to understand the problem statement and the given values. We do as follows:

initial number of balls = 14 + 23 = 37

number of baseballs per box = 12

number of tennis balls per box = 16

we let x as the number of boxes

Total number of balls = 37 + 12x + 16x

Total number of balls = 37 + 28x
