Option C is the correct answer.
What is an expression?An expression is a combination of numbers, variables, functions such as addition, subtraction, multiplication or division, etc.
We have,
Three box sizes:
Small, Medium, and Large.
The volume of the medium box is x.
The volume of the medium box = x ____(1)
The small box has half the volume of the medium box.
The volume of the small box = x/2 _______(2)
The large box has twice the volume of the medium box.
The volume of the large box = 2x _____(3)
Combining (1), (2), and (3) we get,
= x + x/2 + 2x
= (2x + x + 4x) / 2
= (7/2)x
= 3.5x
Thus the expression that shows the combined volume of the three boxes is 3.5x.
